Yes, the AI companies, especially OpenAI and mostly Anthropic, are lobbying for government regulation, partly to exclude Chinese and open weights competition.
It is complicated though.
The guy, Jacob Coxon, you are presumably referring to, may well be regarded as part of Anthropic's own fear-mongering campaign and push for at least partly, maybe largely, self-serving regulation, but at the same time there are many developers working for these companies who say that the internal fear of what they are developing is almost universal.... and yet they keep working on it for whatever reason(s), whether that is pending IPO-riches or some justifcation about needing to develop AI to keep up with an arms race (which they seem to be the ones accelerating).
It seems what we need to do, and perhaps actually will, hopefully before it's too late, is to distinguish AI that is useful for everyday use like coding, and AI that is ridiculously overpowered for things like this and anyways dangerous, that indeed should be government regulated.
It's not an either/or matter of regulate or not - there needs to be some intelligence put into what is regulated or not, just as we allow people to own guns, but not fully automatic assault weapons or rocket launchers, allow people to drive cars, but do not license top fuel dragsters to be used on public roads.
