I don't see it as "do a job because adding value" or "do a job because enjoying the activity".
I think these discussions need to consider if we're speaking in a professional or personal context.
Professionally, I 100% agree and understand that if I'm working as a solutions architect, an engineer, a devops person, a security person, a programmer or any of the other sort of roles I've had, I'm there to get the job done/add value. From that position I can see the value in AI as a tool that lets me get the job done quicker.
Personally speaking, as the nerdy person who actually enjoyed exploring computers since they were able to talk/walk, I'm devastated because I know that if it was so easy for the answers and solutions on a computer to be offered up by AI when I was a kid, I probably never would have spent so much time and had so much fun exploring. Obviously the same could be said about other answer machines that popped up like Google or Wikipedia, but they all still required specific understanding and synthesis to turn into valuable or fun solutions.
But it's the combination of the personal and professional things that also bother me. Modern agentic AI does in hours what tech companies paid eccentric nerds lots to do over days, weeks or months: explore and understand a system (just fun) and then based on that, sensibly improve it (fun and adds value for users).
Agentic AI in tech diminishes the value of eccentric nerds by doing something only they could do, but quicker and increasingly better, and maybe even cheaper. As a mildly eccentric nerd, I can both smile that the world is getting their features faster and more effortlessly, and feel sad that there's less of a reason for me to have fun and/or get paid lots at work because I am less valuable/special now.
