      Only a tiny minority of professional programmers have a clear picture in their minds of how fast modern computers are. 99.9% have next to no idea. How does this affect software that is even conceived? (Ignoring, for a moment, what is actually built, which we know is very slow).

      How big of a problem is it that we have this crucial craft, on which we are knowingly staking the future, and almost none of its practitioners understand the fundamental tool they are using?

      (For the record, I don’t place myself in the top tier re understanding of speed or anything else. I am somewhere in the middle of that gradient between the 99.9% and the People Who Really Know.)

      We see all this bad rhetoric claiming “system X is only 2x slower than native code therefore it’s fast”... but one must ignore rationalizations and look at the actual output, which is several orders of magnitude inefficient. Few people are willing to put 2 and 2 together here.

      The most common objection to these points is "we write slow software because it lets us make things faster and more easily". I agree this is the common belief, but it's wrong. If development is so much easier, why is productivity approaching 0 over time?

      This is a compelling argument, but the claim that productivity is approaching 0 needs more sources. I suspect it's far easier to build applications usable by billions of people than at any other time in history. This is likely afforded by some computational inefficiency.

          Mostly loved the talk, but I feel that this argument that web companies have X employees but their product doesn't improve doesn't say much about developer productivity. Take PyTorch, for example. A lot of work went into it at Facebook but that is not evident to consumers.

          How many things are people working on that don t pan out ? Maybe the productivity of people designing the Twitter web experience is approaching zero. Maybe the twitter managers are incompetent and make the programmers write things that never get used. Lots of confounding vars
