  1. I stand corrected.

    The table in the parabolicarc site I linked says that the separation (and subsequent breakup of the booster) is at Mach 1.5 to 2.5.

    The problem is that the value produced by the robots goes to profits earned by the people owning the robots

    This is only true if competitors don't also install robots. If everyone automates, the profit margins are competed away, and the added value goes primarily to consumers.

    where do the "consumers" get the money to buy that "added value'" if there are no jobs available because the robots do all the jobs?

    Of course, this is only true if we have free markets. Removing barriers to competition is the real solution, not slowing the adoption of automation.

    The main barrier to competition is the fact that as labor costs drop to zero, and all of the cost of a business is the machinery (which in economic terms is capital), it's expensive to enter a new business. The larger businesses drive out smaller businesses (due to economy of scale) and they price out new competitors (who have to pay the start-up costs).

    This should have been covered in your economics 101 class, by the way.

    that is, the rich people.

    The biggest owners of capital in America are pension funds. So if you have a 401k or an IRA, that means you.

    Fine. So, old people with retirement funds are a large portion of the rich people I'm talking about. As a member of the technoclass, you are so insulated in your bubble that you don't even know that not everybody has a retirement fund?.

    People not rich enough to own stocks, IRAs, or pension funds are out of luck,.

    That changes nothing in any of my statements.

    Shortly there will be no entry-level jobs, and after that there will be no jobs, period.

    Too late. The McCormick Reaper already destroyed all the jobs.

    It pretty much destroyed farming as an occupation that provides jobs for most laborers. Right now, farming is under 1.5% of employment in the US. https://fred.stlouisfed.org/se...

    As long as there are other jobs to which the people who were once needed to work on farms can switch to, that's fine.

    What happens where there are no other jobs? What happens after that?

    Your comments aren't wrong, but nothing in what you write changes the problem, or even addresses the problem.

    You seem entirely focussed on prices. Yes, prices, go down with automation. That's not the problem being addressed.

    ...
    Most companies barely make any profit and often run in the red.

    Irrelevant. In the long term, companies that don't make a profit vanish and you can ignore them.

    Sure there are companies that are magnificently profitable, but they can only do that if they have secured their market share and don't run the risk of competitors undercutting their prices and stealing their customers.

    You just hand-waved away some critical pieces of economic theory here. An industry in which most of the product is made by robots, and the labor cost is low, is one in which there is a very high barrier to entry for new competitors, along with high economy of scale. In classical economics, both of these are situations that makes for a "natural monopoly": the companies who already have invested in the robots have a strong advantage over any start-ups, and in the most highly-automated businesses, new businesses can't enter the market at all... without government support.

    For various reasons, this is not a good thing either... but that was not the point I was making.

    Automation reduces total labor required to deliver products and thus drives down prices.

    Prices are not the issue being discussed.

    Reduces mind you, not eliminates, robots after all are expensive for a reason - they are very labor intensive to produce.

    So, you have confidence that robots will eliminate jobs, but won't eliminate the jobs making robots.

    Sorry. They will.

    All you are really doing is shifting labor a step up in supply chain, instead of having people make products, you have people making machines and their parts that make products.

    You're handwaving away the problems. First of all: no. The people making machines and their parts will also have their jobs taken away by robots. Sorry, but when the robots get good enough to take away most of the jobs, they aren't going to stop at just the bottom level.

    The result is that there reaches a point where almost no labor is required for making stuff. The need for labor drops to very low, and there is a vast oversupply of labor, the result of which is that wages are driven down. You can say this is good, because the cost of labor drops toward zero... but what do the displaced humans do?

    As a result, all of us get to afford more stuff.

    Wait: who is this "all of us" you refer to? The cost of "stuff" drops, but not to zero. The number of people employed, however, drops to very low-- you don't need people to make stuff. There is no employment available for most of the humans, You say "all of us get to afford more stuff," but if you're unemployed, how can you "afford more stuff"-- in fact, how do you afford any stuff.

    The answer is, you can afford stuff if you have a share in owning the machines that are making the stuff. If not... you're unemployed and have no prospects for employment.

    As automation makes labor more productive, it is good up to a point. The point at which there are no longer any jobs available for the majority of workers, however, is a point at which we need to rethink a social system that is based on economics that assumes anybody with a work ethic can find a job. How does the system work when there aren't jobs for people who want them?

  4. "This marks the first and only demo mission that Crew Dragon will fly without humans on board."

    Almost.

    Next flight, without crew, is the in-flight abort test, where they launch, but shut the rocket down at about Mach one and let the excape system pull the capsule away. http://www.parabolicarc.com/20...

    Then comes the first flight with crew.

  5. Finally, the beginning of delivery of the implicit promise of Apollo. Late, and not by the government that implied human space travel would become commonplace,

    It is worth reminding people here that this launch, and this capsule, was developed under a NASA contract (And NASA had funded the development of both Falcon-9 and Dragon before the Crew Dragon project as well).

    Not to take away from SpaceX, but just a reminder that this was an example of NASA and industry working together.

    instead of a ****-waving political exercise and cancelled at step 1. Money was of course, an issue, and as usual, private enterprise - and not one yet totally involved in crony capitalism, managed to deliver what the government and their heavily subsidized old-school aerospace contractors could not.

    More specifically, this was an example showing how government contracts can be done right.

    (The booster landing, on the other hand, was NOT a NASA contract-- that was SpaceX all the way. )

    All possible congrats, props, general hip hip hurray and so forth. Just wish I didn't have to wait from childhood until too old to fly for this.

    Agreed.
