From what I've seen, LLMs just accelerate or compound this whole process as well.
Everyone has the same group think, it bleeds into the way the LLM generates code and ultimately it just rots teams.
Corporations were the original AIs. They were slower, a bit less predictable, but they were superhuman intelligence disciplined to produce only the most bland depersonalised slop at all times.
I do consulting, I see lots of teams using LLM's to "speed run to a legacy code base".
Much of what goes on in corporate America is not blindness its accretion. They simply dont have the culture to evolve. The devotion to next quarters numbers and share holder value play a massive part in this.
