Personally I think it is valuable, not only in learning new skills, but in refining existing ones. I've been using AI for past 5 months during my redundancy period, I've learnt quite a lot from it.
However, is there a risk that a current or future employer may see AI as basically cheating - why would they pay me $x where they could get a junior to do the same job? I think it depends on the business mindset, and I know that in the UK there is not a great amount of trust from senior management.
Even after Covid I am seeing more and more companies wanting hybrid models, and to get people back in the offices. I see that as a trust issue, like they basically want you to be heads down for 7.5 hours a day, and they can't control that if you are not in an office.
Maybe though, these are not the forward thinking companies that we want to be working for?
I just thought it was an interesting point and warrants a discussion.
