To me it's self-evident, but is probably one casual step removed from what you'd like to see. I can't point to specific finished or released projects that were substantially accelerated by use of GenAI[0]. But I can point out that nearly everyone I talked with in the last year, that does
any kind of white-collar job, is either afraid of LLMs, actively using LLMs at work and finding them very useful, or both.
It's not possible for this level of impact at the bottom to make no change on the net near the top, so I propose that effects may be delayed and not immediately apparent. LLMs are still a new thing in business timelines.
TL;DR: just wait a bit more.
One thing I can hint at, but can't go into details, is that I personally know of at least one enterprise-grade project whose roadmap and scoping - and therefore, funding - is critically dependent on AI speeding up significant amount of development and devops tasks by at least 2-3x; that aspect is understood by both developers, managers, customers and investors, and not disputed.
So, again: just wait a little longer.
