This is a circular economy that makes everyone look good. Almost all of these enterprise companies are sitting on top of so much of tech debt that in any realistic scenario they cant really patch vulnerabilities if they are even in double digits. A lot of these companies would not even let their valuable enough code to be ingested by LLM's.

At this phase no company would risk their brand by calling the product as ineffective. The big players are in it together and small ones have no option but to play along.

Nevertheless collecting the historical wisdom and running it at machine scale does have a lot of benefits for sure. The only question is the signal to noise ratio, machine is doing what humans did, just at a multiplier speed and with a lot more context than what a normal human can hold.
