While waiting for the optician I had a chat with the technician. Whom is not interested in becoming an optician (so it is not a "using students to save money - though it might further their career" thing even). It is de-skilling.
I now have to trust some LLM to interpret my eyes and not hallucinate the need for surgery (and trust it hasn't been instructed to aggressively up-sell, using the ignorance of the technician to suggest things that are not needed).
