So it all hinges on an empirical disagreement you have with them. There's nothing particularly unserious about that.
There is quite a lot of mathematical research into agentic behavior that suggests a combination of instrumental convergence and the orthogonality thesis make it very likely a superintelligent agent will have arbitrary goals that lead it to attempting a takeover of Earth's resources to achieve them.
There can't be a science of superintelligence because it doesn't exist yet, but the best theories I have read seem sound, similar to how 19th century theories of anthropogenic climate change turned out to be sound.
Even the sci-fi scenario assumes there is a discrepancy of capability between attacker or defender. If the 'attacking' system is (by some reasonable measure), 1000% as capable as a human, and the 'defending' systems are 60%, then it is a problem. If the 'attacking' system is 1000% as capable as a human, but there are hundreds of thousands of systems that are 900% as capable as a human, it's probably not going to take over everything successfully.
So unequal distribution of AI technology, and lax regulation and opacity of the biggest companies which actually make the risks the worst.
I don't think the "AI Safety" people are "unserious and out of touch" - I think they are actively making AI Safety problems worse by being advocates for consolidation of AI development and lack of transparency.
And the non-techies who have seen Terminator and other movies blindly line up behind them…
What worries me the most (enough that I left tech to work on this full time) is bio. The amount of effort needed to defend against a pathogen can be many orders of magnitude higher than the effort needed to create it, and the upstream bottlenecks are both less limiting and mostly undefended. We've been safe so far because bio is very hard, but "rare expertise" as a gatekeeper is on its way out.
But those things fall in a category of "things that are awful and I'd like to see solved", which is different than "existential risks which could see my kids dead, and there's nothing I can personally do to shield them from it".
Instead, they are focused on stuff like "can I ask the AI to help me build a nuclear bomb" or "is the AI willing to generate pornographic stories", which is neither trying to protect us from unleashing a vengeful god NOR preventing (in any honest way) the today-level problems you (very correctly) bring up.
We should be paying at least as much attention to the people who want to use AI to consolidate their wealth and power, and how they’re trying to do that. They’re a clear and present immediate danger to our societies, not something we can only speculate about. And if we deal with them, better control of AI will be a side effect.
And why not? It seems there is, indeed, one born every minute, and technological progress only accelerates this phenomenon.
