AI Fatigue and Time Estimation

Anyone having fatigue from AI ? I careful created and rolled out project in two week at work. Someone argued that with AI it should have happened in 2 day and they argued with examples etc. Point is with AI it has become so hard to estimate timeline. It all now depends on how good you are at using AI tools. We use co-pilot at work and I still feel we cant blindly just take any code it spits out, we still have to review it and make sure it does not create bigger bugs in the system. I am seeing trend where managers are just blindly expecting devs to copy paste code from AI tools and speed up the process.
