No evidence given.

In my opinion, someone who argues that the LLMs will keep on improving is a gullible sucker.

Someone arguing that LLMs will keep improving may be putting too much weight behind expecting a trend to continue, but that wouldn't make them a gullible sucker.

I'd argue that LLMs have gotten noticeably better at certain tasks every 6-12 months for the last few years. The idea that we are at the exact point where that trend stops and they get no better seems harder to believe.
