I agree. The long term effect will be a devaluation of knowledge work more broadly. It's a rich irony that so many people clamor to these tools when their constant use of them is more often the thing undoing their value as knowledge workers: flexibility, creativity, ability to adapt (intellectually) to shifting circumstances and new problems.

A downstream effect will also be the devaluation of many accreditations of knowledge. If someone at a community college arrives at the same answer as someone at an Ivy League or top institution through a LLM then why even maintain the pretenses of the latter's "intellectual superiority" over the other?

Job interviews are likely going to become harder in a way that many are unprepared for and that many will not like. Where I work, all interviews are now in person and put a much bigger emphasis on problem solving, creativity, and getting a handle on someone's ability to understand a problem. Many sections do not allow the candidate to use a computer at all --- you need to know what you're talking about and respond to pointed questions. It's a performance in many ways, for better and worse, and old fashioned by modern tech standards; but we find it leads to better hires.
