It's not about what they wish would happen, it's about what they think will happen. In my view they are acting precisely like they believe they will be making a proportion of developer pay by making them more productive rather than replacing developers. I think they understand that the alternative doesn't really work out for them or anyone.

Even if they believe that their systems will eventually tank employment and replace developers rather than augment meant, the fate of Astral doesn't matter at all in that scenario because a) nobody has a job, and b) you can build your own uv replacement for $20.
