You can only make employees more productive.. this in turn could, in theory, lessen the need for developers in the long run, but it assumes the company will not bother to use the extra bandwidth for other projects.
This is exactly what would happen if ChatGPT was actually a productivity boost for senior devs. I don't know why some idiots on here keep insisting businesses want to get rid of people when that's not how the game works at all. Extra work capacity will always be used. Regardless of what payroll costs, what's always more important is the ROI.
And exactly like this some future brain implant thing will also put another layer of pressure. People will get it as it'll give them an edge on certain fronts.
