Programmers Aren't Productive Anymore [video]

Important facts well presented.

But actually we (still) can run programs on Windows without signing, or did I miss something?

I was looking for a recent programmer productivity study confirming the claims of the talk, that moving to higher abstraction levels reduces (instead of increases) programmer productivity, but I didn't find one. Maybe someone has a hint.

But I found e.g. this one (https://www.software.com/reports/future-of-work) claiming that when people work at home they require less time to do the same programming work than in the office, which indicates that not the technology, but the work culture is the issue.

Actually even Ken's statement supports this; his productivity skyrocketed when his family went to vacation, why he was able to write Unix in these three weeks.
