Such a cool guide to such a bizarre problem we live in… Companies forcing features that nobody wants, but that are also expensive to operate and cost real money to run? Market can definitely stay irrational for long.
Alternative hypothesis: people do gradually use these features, but HN became a weird anti-AI bubble for some reason. I mean, many of the features had previous pre-AI attempts. They all sucked much more. This is the first time they have a remote chance of working (but in many cases, timidity or cheapening out is still making them barely usable - which is why 99% of the cases it's still much, much better to throw one…
The pro-ai posts here have got to be 50% bots, i'm convinced. I have yet to see a single artefact of AI that was remotely impressive. Fancy markov chains do not intelligence make.
