I talk to extremely experienced programmers whose opinions I have valued for many years before the current LLM boom who are now flying with LLMs - I trust their aggregate judgement.
Meanwhile my own https://tools.simonwillison.net/colophon collection has grown to over 120 in just a year and a half, most of which I wouldn't have built at all - and that's a relatively small portion of what I've been getting done with LLMs elsewhere.
Hard to measure productivity on a "wouldn't exist" to "does exist" scale.
You want me to say "this stuff is really useful, here's why I think that. But lots of people on the internet have disagreed with me, here's links to their comments"?
What in the wooberjabbery is this even.
List of single-commit LLM generated stuff. Vibe coded shovelware like animated-rainbow-border [1] or unix-timestamp [2].
Calling these tools seems to be overstating it.

I wrote more about it here: https://simonwillison.net/2024/Oct/21/claude-artifacts/ - and a lot of them have explanations in posts under my tools tag: https://simonwillison.net/tags/tools/
It might also be the largest collection of published chat transcripts for this kind of usage from a single person - though that's not hard since most people don't publish their prompts.
Building little things like this is really effective way of gaining experience using prompts to get useful code results out of LLMs.
But it was already a warning before LLMs because, as you wrote, people are bad at measuring productivity (among many things).
