3D printing for individual parts is to the point where the 3D printers can manufacture useful parts. Most major car manufacturers have a 3D printer farm hidden away somewhere for rapid prototyping (it reduces the the turn around time from going to a machine shop).
The issue is the 3D printers can't manufacture parts fast enough to keep up with demand of a production floor. To produce one part at the volumes needed the car manufacturer would need a huge farm of 3D printers and technicians to keep the printers running 24/7. The advantage of this system is the part could be fabricated on site reducing the supply chain for that part. If there is one thing manufacturers hate it is complex supply chains and multiple suppliers of parts, both of which are outside the control of the manufacturer.
If a manufacturer could bring parts back under its own roof (or the next building over) and the revision period for a part could be reduced from weeks to hours, they would do it in a heart beat. It's all a question of being able to do it at a scale that is sustainable for the manufacturer (and cheaper).
It doesn't matter if the wall you build is thirty feet high and six men can walk abreast if you can kick in a door. The weakest part of a wall is always the gates and these kinds of bills are trying to require extra doors with standardized locks are used. No way this can be abused.
I expect that hacking a car's vehicular AI will change its insurance rates. Insurance companies charge insurance based upon known risk. A vehicular AI that has been rated by an independent rating agency (UL, etc) is a known quantity and an insurance company will be willing to insure it.
A home spun vehicular AI will be considered an unknown risk and will be treated as such by the insurance companies. If you want to roll your own vehicular AI, feel free but you'll be responsible for having the AI rated and certified. Otherwise the vehicular AI will be treated as a "High Risk" AI and your insurance will reflect that.
To my understanding PE stamps are not normally used for machinery design or automotive design. Those designs go through a huge number of regulatory hurdles and certification processes (crash test, MPG, fire control, UI layout, handling and roll over, electrical breakers, etc etc etc) that take the place of the PE stamp. If you were going to require PE stamps for an automotive design you would end up with thirty or forty stamps for each part of the design - engine, transmission, suspension, drive train below the transmission, electrical, outer shell, interior layout, crash management, pollution control, specialty sub systems within each of the primary systems. The company that is designing, assembling and selling the finished product is liable for all of the certifications and regulations that are required to put a car on the road.
The reason why there are so many certifications and regulations around a mass manufactured item (cars, toys, appliances, garden tools) is the sheer number of them put on the market. Because someone is producing 500,000 units of a given thing means that more oversight is required because more people could be injured if there is a mistake or oversight in design.
Most cases I see where a stamp is required: The item being designed is a one-off or custom job. You need someone who has the authority to make the call that something is safe and will perform as advertised.
Hell, my PE application (still applying, not approved to take the exam yet) doesn't list Automotive as an option. Maybe you could file care design as an Industrial PE item. Everything else doesn't fit (Civil, Nuclear, Aero, Mining, Architecture, Chemical, Petroleum, Fire Protection, Electrical, Metaullurgy, HVAC, or Naval).
Cases of arson, lynching, beatings, killings, cross burnings and voter suppression in an organized manner against a specific segment of the population? These activities have been ongoing for over a hundred years in a systematic manner? The frequency is down but it still occurs or is overlooked. I would call that terrorism at the very least.
Having worked inside the industry for a while all I see is Fast and Cheap from owners. So I may be a bit jaded. The same with my comment above about having to police other engineers who have attempted to slip in changes under the wire.
I have heard of traditional post and beam. I haven't built any buildings with it. The discussion was about how different building systems become outmoded by newer systems that get the job done faster or cheaper (all other things being equal).
Post and Beam is a mature building system that has been in many cases outmoded by a faster, cheaper alternatives (in field stick building or in factory module construction). You can find "traditional" post and beam builders out there but they cost more than 2x4 construction. I expect they are doing everything they can to stay cost competitive with the cheaper alternatives. I wouldn't be surprised at all if they are using CAD/CAM/CNC to cut all of their joints and reduce man power. Even so they fall into the high end market for housing construction. Its basically a niche product that you have to seek out and be willing to spend extra to get.
Furniture and joinery is an art I will never have the time to practice to a fine level of precision. I am glad that people still practice it.
Yes, that is all locked in in PDF or an approved format that cannot be edited after the fact.
I have seen some sleazy attempts by architects and engineers to slide things in under radar. Undocumented changes between Bid sets and contract sets for instance. Luckily I was only the commissioning agent on that. You can bet there was a lawsuit over that little stunt when it got caught.
I think I said that advances occur very slowly in the construction industry. Mortise and tenon has been abandoned. Why? Because something came along that was cheaper/faster with all other things being equal. Eventually something will come along that will replace nails and glue. I don't know what it is.
I won't use a technology/system that hasn't already been vetted through the insurance and rating agencies (UL, et al). If you come to me trying to get me to schedule/specify a product that hasn't made it past the rating agencies I'll throw you out with the bath water. I don't have time for untested and unrated equipment.
There are plenty of competing technologies that are tested and rated (have the UL mark) and are still trying to break into competitive construction in a big manner:
Precut lumber (mostly in use in custom home construction but not much elsewhere)
Engineered lumber products (it shows up when space is the constraint)
Automated concrete laying (Not matter what people say, this is still experimental)
Pro-Press fittings for refrigerant piping (just came on the market, the contractor is willing to give it a go with our blessing)
Integrated duct/insulation systems (This keeps coming up as an alternative to galvanized and keeps getting shot down)
Alternative grease duct systems (Fire rated systems that take less space)
3D printing (This is a novelty right now, but one that works. A couple of architects have specified it for difficult metal fittings in unusual buildings).
I could name a half dozen other technologies that are coming into maturity and their adoption is based upon preference or "We did it this way when I was a whipper snapper and you will to".
Paper plans are there for a different reason: Paper plans are stamped and signed by the architect/engineer and are the record/permit/contract set of construction drawings. I can't see any contractor worth his salt saying "I'll build that building based on a computer file that can be updated by remote push down"; there are to many chances of undocumented changes, issues on change orders and lawsuits over undocumented changes. And its not like engineering, architecture and contracting don't have enough of those problems.
I see is that there is plenty of dimensional lumber being used in that structural system. Different areas of the world use different dimensional lumber sizes than the US. Some areas of the world don't have dimensional lumber. Some areas of the world don't have the infrastructure required (dimensional lumber, CNC machines, trucks to ship the lumber).
I have concerns with the long term stability, durability of the structure. Nails and glue have been in use for a while (hundreds, if not thousands of years) because they work.
As a construction experiment in using new technology to find new ways to design and build buildings it is an interesting experiment. I applaud them for trying this. Its like looking at the concept cars that Ford, Nissan, Subaru, etc release every year and are loaded up with all sorts of outlandish features, some of which will obviously never get to production, some need some refinement and some are pretty good. I have no problem with someone deciding to build the equivalent of a concept car. Don't be surprised if your concept takes a long time to be adopted by the building industry. It will take that long to be vetted by architects, engineers, suppliers and contractors. Hell - it took almost twenty years for contractors to adopt Pro-Press pipe fittings as the preferred option over copper sweated fittings (and that is just copper pipe).
If you want to look at a scene that plays with continuity: Find the scene where the cops (Leslie Nielson & co) are in the cruiser. The conversation is entirely blase. The thing to look for is the donuts and the coffee cups - they migrate around, get refilled, change color.
It must have driven the continuity people nuts, it was intentionally screwing with the one subject they work very hard at getting right.
Most competitors are on very regimented diets. The last thing they want to do is upset their digestive tracks in the days leading up to a major competition. Teams routinely bring their own food with them. This was a "story" during the Russian winter Olympics when the Russians tried to put a hold on Chobani yogurt that was coming in the country by the pallet (amoungst all the other food coming in). The news was trying to drum it up as a disaster (right next to the wild dogs wandering around in the hotels).
I expect to see the Japanese Olympic committee push the idea of Fukashema produce; the teams will mouth polite noises at the appropriate points - and then continue with the diets that have been developed and tracked for each team member.
As competitors are knocked out of competition you will see more variation and experimentation in their diets. Anyone that is still in competition will be adhering to their diets.
It *might* be possible to use an overlapping LIDAR system to pickup on small flying objects. The number of sensors required and the systems integration required would be an enormous task though.
Bullies are the flip side to good values. They come at you all sizes shapes and methods. All they want to do is challenge your values and tear you down to their level. You can't do this you're a girl. You can't do that you're a wimp. You cant do this because I can pick on you. I'm going to pick on you just for spite. I am going to stand between you and your goals just to make you miserable.
Your daughter will have to learn to stand up for herself more than she expected to at her age. Bullies like to prey on the apparently weak and defenseless - children losing a parent fit right into that category.
She has to know that being willing to speak up for herself, and being willing to ask for help when things are beyond her control are good skills to develop and use. Bullies can only be dealt with by standing up to them and forcing them to back down. Any type of appeasement action against a bully only encourages them.
Be careful of approved authority figures as well. They can act as bullies as well, just with tacit approval that people find difficult to challenge because they are the approved authority.
At this point in a career, recruiters are the way to go. Until a solid collection of connections through work experience can be built up recruiters can find jobs faster that you can.
At the same time if I am comparing twenty resumes and one says: 5 years relevant work experience and the other nineteen say: 5 years relevant work experience and a BS in comp sci the one resume that doesn't have the BS is going to get passed over on the first pass.
When an HR rep has to review 20-50 resumes for a job opening any deficiency or typo will get you passed over without a second thought.
Some of these areas are so poor that if you show *any* signs of attempting to improve yourself, or get up in the world you will be beaten, or killed for attempting to upset the current powers that be. And since powers that be are the local strongman, warlord or government you keep your head down and avoid drawing the attention of the guys with guns.
That's an awfully nice garden you have there, mind if I take all the fruit off of it? And sometimes not even that, just having to defend your improvements from the locals who want your improvements for yourself.

Sounds about right. Painting the door the same color as the wall works as camouflage right up until someone gets up and touches it.

We're had cross burnings as recent as 2006 with intimidation and violations of the fair housing act. That recent enough for you?

Always get a contract that stipulates the deliverables. It controls the liability and helps insulate against lawsuits.

Does it get food and potable water?
Then get people cell phones with SMS options. They are portable, easily charged and CHEAP.
