    I'm starting to wonder if any of this is better than local newspapers, where there's an editor with oversight over all content...

    You can run a lot of these on e.g. M1 max 64gb

    Erm that's higher than the healthy BMI range, so not "fairly light". >25 is considered overweight.

    On the other hand, taking backwards compatibility so seriously is a big part of the massive success of Python

    It's very clear that the consumer is getting a worse experience than what is technically possible. There is no good phone-slash-laptop, purely because it's less profitable than loc…

    I couldn't see any citations or references in that video or its description. It presents it as him solving the problem himself, but I'm sure other people have written about solving…

    And the news just now is that the chair of the OBR has resigned because of this [1] [1] https://www.bbc.co.uk/news/live/cly147rky81t

    Hmm it can capture more than just single words though, e.g. meaningful phrases or paragraphs that could be written in many ways.

    I agree, the post above you is patently wrong / hasn't read the paper they are dismissing. I also got multiple downvotes for disagreeing, with no actual rebuttal.

    I think the main thing to clarify is: It's not a uniform distribution after the first measurement, t_obs. That enables us to update the distribution, and it becomes a decaying one.…

    Ah no, it is the Copernican principle, in mathematical form.

    Comment #45646855

    Yes that's pretty much it. There will be a decaying probability curve, because given you could fail at any time, you are less likely to survive for N units of time than for just 1 …

    (Just to expand on that, it's true not just the for the first token. There's a lot of computation, including potentially planning ahead, before each token outputted.) That's why sa…

    That's a paradox that comes from getting ideas mixed up. The most likely time to fail is always "right now", i.e. this is the part of the curve with the greatest height. However, t…

    That's inverted, it would be: If: P(1 more minute | 1 minute so far) = x Then: P(1 more minute | 2 minutes so far) > x The curve is: P(survival) = t_obs / (t_obs + t_more) (t_obs i…

    Ah, that's not correct... That explains why you think it's "trite", (which it isn't). The distribution is uniform before you get the measurement of time taken already. But once you…

    Comment #45642654

    You've added some useful context, but I think you're downplaying it's use. It's non-obvious, and in many cases better than just saying "we don't know". For example, if some company…
