Manager here. Did not fire anyone (and hope not to), but I am starting to look into implementing GPT-4 as a part of our development practice and, potentially, reduce future hiring. This might have a positive impact on our engineering budgets, which are always tight. Many of my colleagues are doing the same - this has been a cooler topic with other managers for weeks now (strange how progress is now measured in weeks).

At this point, this would only affect engineers who don't understand our subject area (biotech) and are relatively junior (in the sense that their output is not much better than a GPT4 output reviewed by a more senior dev).
