If every employee had an AI assistant that doubled their productivity, would companies hire fewer people or expect twice as much work?

I’m a 35-year-old in Seattle, and I’m genuinely terrified that I’m already becoming too old for this industry. I looked around our all-hands meeting yesterday and realized that except for upper management, almost everyone on the engineering team is fresh out of college age. They can pull all-nighters without blinking, while my back hurts if I sit in the wrong chair for two hours. Are we all just silently sliding toward an expiration date once we hit our late 30s? How do you stay relevant?

Sad, my LinkedIn profile rarely gets any views and even with Premium only appeared on 20 searches last week😥

I had two interviews this week and one screening call but I still don't feel confident that i will reach the next round. I have 20 years experience working with infrastructure (physical hardware) but have a AWS cloud practitioner Certification. The jobs seem more based on Workflow, process, new technologies. Yes, I can do those things but i fear my experience in those areas are not as prominent than another person. I feel stuck in a place I want to transition out of. How do i break out?

I’m realizing that my coworkers who are being hired externally are making so much more money. I’m now thinking what’s the benefit at staying g at a company and rising the ranks?
