He touches on this in his first video. The workaround is we are now getting into a regime of computing where exact reproducibility is not necessary. It will take a while though. It is still quite hard to remove noise for opamp circuits.

> we are now getting into a regime of computing where exact reproducibility is not necessary. I think that is a myth. Predictable, reproducible and explainable outcomes are the holy grail of computing, in particular in AI. If stochasticity is desired, there are methods to inject it, with precise control of the level of stochasticity and the distribution. This level of control is absent in analog computing. Device mis…

I said exact reproducibility. Every time you add numbers your neurons likely fire in slightly different ways, but the end result is what is reproducible and useful.

He's not totally correct because, like I said, the way we think of analog computers right now is likely not going to get us to where we need to be. Noise is a huge problem. Our own neurons do not seem to use continuous voltage, for example, and use pulse density coding, at least for some of their operation.

Something about Veritasium absolutely rubs me the wrong way, and I generally like Youtube education creators, but his videos are borderline unwatchable for me. Does anyone have an explanation for what it is about his videos that is so grating?

All of his videos that I've seen have a weird thing where he challenges people to explain something, and then he reveals he was talking about something else and their explanation isn't relevant. This is just https://xkcd.com/169/ His videos don't strike me as intending to educate. They strike me as intending to show how much more clever he is than you - and it's entirely that he came up with some weird gotcha that pe…

That comic reminds me of all the times I've seen someone pose the Monty Hall Problem without mentioning that the host always reveals a goat on first round.
