Not really, the US is still a bigger market, but even leaving that aside, I see more handwringing from actual EU citizens as to how this will impact their local markets and jobs, than from anyone actually in the US [0][1]. It's more like those in the US are simply pointing and laughing at the EU consistently shooting themselves in the foot rather than any actual disdain from them. It actually reminds me of those who make fun of cryptocurrency while those who've "invested" in cryptocurrency think we're just "mad" that we didn't make "gainz." No, mate, we're just laughing at people who fall for such misfortune.
HN is not typical of the general population of Europe, not even within the IT community. It self-selects for certain kinds of people. There are other IT communities, such as the CCC, that do not at all share the libertarian bent that HN tends to have.
I'm from the EU, and I'm not afraid that AI regulation is going to make my job disappear. There are other EU laws / rulings that I'm much more worried about (e.g. chat control, or for a mundane example, mandatory time tracking).
Meanwhile, if people from the US are "laughing at the EU consistently shooting themselves in the foot", I kindly suggest taking a close look at your own country before judging others.
