The comment was unclear, but my interpretation (also my opinion):

1) there are inherent risks involved with developing AI,

2) there are benefits to developing AI,

3) thus, it's entirely possible that the downside from the risks outweighs the upsides. In this case, the correct thing to do would be to not develop AI at all.

Regarding 1), there are many non-existential problems with AI that are already causing societal harm, i.e. debasing truth via generated videos and images, AI girlfriends, overwhelming quantities of slop content, unemployment, record carbon emissions, etc.

Regarding 2), I'm not personally convinced that the upside is there for the average person. I really hope to be convinced otherwise however.
