In addition to the bot farms, many in the AI related fields have plenty of perverse incentives to participate - for reasons other than genuine interest. That's why I don't read those threads, although the marketing angle is easy to see it's also prevalent and laboring to filter out all 90% of it isn't worth the effort.
In general, if you are observing a community, and you see what looks like a contradiction like this, almost every time what you're actually seeing is Two Guys: in this case, one portion of the HN userbase that hates datacenters, and another portion that has to change their underwear every time Anthropic puts out new release notes.
Very few communities like HN are genuinely monolithic, and very few people are going to hold such contradictory beliefs within the same individual.
The most effective enemy propaganda is called "sticker shock". When the sticker goes up in a week, it's double propaganda. I'm fully onboard with the idea of stopping the propaganda producers from continuing to do it.
On the other hand, the Chinese lag way behind in data centers. Odd.
Clearly you're in the last quarter of the demographic described.
