Probably meaning C-Suite thought productivity was up because of AI, either because A) metrics showed high AI usage or more commits/LOC or B) we're mandating AI usage, why wouldn't it increase?
For a lot of C-suite there has been more of a fast-follow approach to AI. CEO hears 3rd hand what competitors are doing, tells his CTO to "do AI" and "hire a head of AI".
So a lot of motion (do AI) was created without a destination (product outcome). The motion was what was being measured (we are doing AI).
What do you mean placebo effect? They thought things were created with AI while they actually weren’t?
