So far where I work its the Instant Pot, at least for the non-devs. We rolled out Claude & Cowork to the masses after a brief pilot. It was about a solid month and a half of heavy usage and then suddenly usage fell off a cliff. Once it stopped being a cool new toy, people just didn't find a use for it.
A few mundane things got automated, but these were just back office admin type work. Nothing that's going to show on the P&L. Yeah those people now have a little more time for other things, but those other things are also not revenue generating. No FTE got replaced by it so in the end they just paid for a bunch of administrative positions to be a little less busy. Great for the workers who are now less stressed, but almost no impact on the business financials except there's now yet another subscription.
