The problem is that this is just another instance of trusting that "the market will solve all our problems."

But that's based on "spherical economy in a frictionless vacuum" type assumptions.

In the real world, in addition to the problems others have noted of it being hard to identify and fix the specific sources of problems, we have so much consolidation that it doesn't matter if something from any of the tech giants starts getting buggier and slower. What are you* going to do—switch from Windows to Linux, just because it's getting a bit buggy? Or worse, switch away from Banner, or Salesforce?

We cannot depend on "market forces" to prove whether LLM-assisted coding is actually a good idea. We have to push for universal personal accountability for the code we commit (at least internally; I'm not calling for legal liability here!). Which is, unquestionably, going to be a huge uphill slog.
