I've never seen an AI critic say AI isn't "useful in any field whatsoever". Especially one that is known as an expert in and a critic of the field. There may be names that aren't coming to mind because that stance would reduce their specific credibility. Do you have some in mind?
The post you replied to was asking for examples based on the general critical discussions they have seen.
And no offense to the GP, but they clearly aren't an expert in the field or they wouldn't be asking.
Probably should have replied directly to the post you replied to as much as yours. Was just pointing out that "not useful in any field whatsoever" is not something I've seen from anyone in the field. Even the article doesn't say that.
