That's not wrong. There is a lot of hype-driven development in the programming world. People are always jumping on the latest web frameworks and such. A little bit more stability is not a bad thing.
That being said, I think that people underestimate how fast LLM technology can evolve. At the moment, lots of training data is needed for LLMs to learn something. This may not always be the case. In 2 to 5 years, it may be possible to train an LLM to be helpful with a new programming language with much less data than is needed today. No reason to assume that the current situation is what things will be like forever. It's not like this technology isn't evolving incredibly fast.
