    The question at its heart is not about object avoidance in the article...it's about choices between objects. And that requires identification.

    Such dichotomies are not realistic. When defined they are always spelled out like "The car is going 300 mph in a 30 mph zone, with lines of parked cars on both sides, and low visibility. A passing plane looses a set of seats, unoccupied, landing facing away from the car at a distance of 50 foot. At the same time, a kid runs out from between parked cars. The road is completely blocked by the child and the seats. What do you hit?"

    Yeah, it takes magical couches appearing from nowhere and impossible starting parameters of overly unsafe driving and such. Any "realistic" scenario leaves one clear point of action that is best for all. For 99.9%, braking within your lane is the best action. That last 0.1% could always be the wrong answer and the sum total would be much better than leaving humans in control.

    I was always taught Hubris from the Greek tragedy perspective. Hubris is pride, especially when that pride leads to their own downfall. A sitting king who makes bad choices because they are too prideful isn't "hubris" until one of those choices becomes their downfall.

    So in the Greek Tragedy definition, it can't be hubris until after the bad decision results in a problem. Aside from some bad P.R., I don't see any problems caused by the excessive pride of the US, or those who work for it, so hubris can not yet be the accurate word.

    This would not work, for the simple reason that there is no way to safely move on most roads, if you assume that everyone else is a malevolent actor, waiting to slam into you as soon as you place yourself in a position from which you cannot avoid him.

    You can assume rational actors. They aren't, but it's a valid assumption.

    But some times, the other car will blow a left tire, or the other driver will have a heart attack and lean on the wheel. And an accident will be about to happen.

    Unless you are on a narrow road with barriers on both sides and all lanes full, with no emergency lanes or available space at all, then your "worst case" is still trivial.

    If I were programming it, I'd program it to minimize damage. That means avoiding a head-on, and not avoiding traffic with a small speed differential. If the person beside you swerves into you, that's trivial. You hold speed and steer into them, both cars traveling foreward, and nobody injured. The human response is to swerve away from them when not safe to do so, and kill themselves by hitting a tree or wall, while the heart attack victim kills themselves on another tree ahead.

    But, for some reason, saving multiple lives and minimizing damage is undesireable because "OMFG, the autonomous car deliberately hit the other car!!!!"

    When a collision is imminent, the car should try to avoid hitting anything. If it cannot, it will have a fail mode, which I bet dollars to donuts will be "Maintain heading and reduce speed". Why? Because that is the safest setting in many situations, because it is what you want everyone else to do, and because it is easy to mandate it by law.

    It's also better than the human response in almost all situations. I know of multiple people who killed themselves avoiding animals on the road. I know of nobody who died from hitting one. The statistics aren't kept in a manner that makes it easy to see if my experience is typical or atypical.

    My concern here is how controlled that lab environment is. I did my fellowship in an ID research group that had a BSL3 lab in the unit and given the number of containment breaches they had, you should seriously question the the wisdom of conducting the kind of research

    The real problem is that the security levels are lax. They are more design rules, not operational ones. You can design for any level and get a certification, but so long as the gear is working, if the processes and people don't work well, you'll end up with a significantly reduced actual safety level. Properly done, you end up with breaches being events like "meteor struck building, destroying air handling systems, and creating a large breach in the envelop" events. Triple redundant power isn't uncommon, but no amount of redundancy can ever be "100%". 100% is impossible. There's always the chance of something almost impossible happening. But when you are examining the chances of an airplane crashing on the building during a hurricane, and alien invasions for the most likely breaches, you are doing good.

    Reminds me of the Pentagon construction. When they re-built it, and strengthened it, the strongest part of the outside was the glass. A .50 cal would penetrate the multi-layer wall with lethal force, but wouldn't breach the windows. The asumption was any sniper would use visual sighting (as the multi-layer wall made any current scanning useless). So they'd prefer the window shot. In the 9/11 wreckage, they found intact glass panes, which was used as "proof" by the dumb that it wasn't an airplane crash.

    Wires are generally sent the same business day if processed before 5:15 p.m. ET for international transfers and 6 p.m. ET for domestic transfers.

    Have you ever had a banking account? That sentence means you'll see it in your account 10 a.m. the next day, maybe. It's not "same day" under anyone else's definition. The banks send the transfers into an escrow-like account that's cleared midnight. The receiving bank gets it at midnight, but most do sanity checking, and have a human the next morning "approve" the overnight transfers. Because it's possible that someone who knows the fraud rules could abuse them. It's happened to them before. If they have a fraud limit of $10,000, then those might get flawed, but 100,000 transfers at $9,999.99 wouldn't get caught. So they keep a human in the loop, rather than refining fraud filters.

    Then, once they are approved by a human in the morning, they pop in the account sometime later that day. "Same business day" means "tomorrow" for the banks. This just proves your ignorance of banking.

    The problem is that FICA, etc. is listed as an "employee" tax when talking to employees, and an employer tax when talking to employers.

    Also, a small business owner does not "pay" sales tax. It collects sales tax paid by the end user, then passes it on to the "government". Counting that is a lie.

    Also "the government" changes depending on the situation. Property taxes are paid to the local government (possibly state, in some places). Sales tax is "collected" for the local and state governments, and income taxes/FICA are paid to the feds.

    So the question is, what was (business income tax)/(total gross revenue)*100%?

    That's the number that's interesting to most people, and it's usually under 1%. The largest payer of corporate income tax last year was Exxon. They paid about 7% income tax (based on gross revenue, the way "people" are charged).
