Your source is a liar. Some examples: - After lying about SpaceX launch costs, he later posts screenshots of articles. One of those articles had the true launch costs. The image was photoshopped to remove this launch cost. - When posting pr

Very bad source. I go into why in more detail in this comment, but to keep it short: his numbers are lies and he knows it too - some of his screenshots are photoshopped to preserve his narrative. He has an agenda - an anti-Elon Musk agenda

It can help to understand why some people think inaction is an action by abstracting the problem such that you can model it in a computer using standard decision problem algorithms. When you do that you have an initial state and you have tw

Cramming the night before an exam isn't the same thing as teaching either. If we need to accept that teaching is always the outcome of the worst performing learners it would follow that schools don't teach children to read. After

Having thought about this for a while - this is on you, not me. The idea that some computer programs take too long to finish if their input size is really large isn't a complicated one. You try to discredit the existence of this basic

If error in abstraction is never right to teach as the OP claims, then you're saying that computation using numbers shouldn't be taught. It literally doesn't matter what computer programming language you use. Every single one

Abstractions are useful because they simplify and if you don't allow error you don't allow maximization of simplification. You can formally relate this to learning problem formulation complexity. When you do you encounter things l

No, because games can be competitive and therefore there is an adversarial selection effect. If there is a motion which is hard then it follows that the other players will force you to make it. This isn't theoretical. It isn't unc
