That middle graph is absolute fucking bullshit. AI is not fucking ever going to replace 75% of developers or I've been working way too fucking hard for way to little pay these past 30 years. It might let you cut staff 5-10% because it enables folks to accomplish certain things a bit faster.
Christ on a fucking crutch. Ask developers who are currently using AI (not the ones working for AI companies) how much time and effort it actually saves them. They will tell you.
