This is one of the issues with LLMs in dev IMO.

You either have the case that tech moves on and the LLM is out of date on anything new, so adoption slows or you have tech slowing down because it doesn't work with LLMs so innovation slows.

Either way, it's great if you're working on legacy in known technologies, but anything new and you have issues.

Can I write a spec or doc or add some context MCP? Sure, but these are bandaids.
