This is it. This is what everyone is enabling by humoring genAI: you spend months writing something that took you years to get at, for an opaque algorithm that a few control to spit a number and cut you off right there and then. This is what we're up against 🧪

This interview with @timnitgebru.blacksky.app does a good job puncturing some of this BS. I think the private sector often profits off of just this sort of move: hiding ‘expertise’ behind proprietary doors and then making public claims that can’t be scrutinized is par for the course in business.

With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.
