If it takes weeks to get some code into production, I understand how AI can enormously speed up things. Yes, AI can be fantastic but if people claim 100x increase, something else is majorly fubar.

I don't know what OP means. The deployment pipeline takes weeks or the release process?

The latter is probably the case for most enterprises.

Getting releases deployed into the testing environments, much less production, requires coordination, testing, reports and sign-offs.

Of course this can normally be expedited or bypassed for incident management and critical fixes.
