All the companies have the same access to AI, and AI is making them all better at doing what they were doing before (writing software). So some companies that use AI really well may be able to take market share from other companies that are slow. But I think this might just lead to a more intense competition for customers.
Kinda like what happened to music after digital recording became the thing - we have more music than before and the music is better, but being a musician became a much more intense competition to find an audience.
Perhaps some new markets could be entered that weren't feasible before?

Interesting to look at, a decent example for sure.
I bet every company is finding up how to level up their employees via AI, so that they can use less of them in the future.
So even without increased revenue, AI has its (mis)uses.
