As a person who has been managing software development teams for 30+ years, I have an observation.
Invariably, some employees are "average". Not super geniuses, not workaholics, but people who (say) have been doing a good job with customer support. Generally they can code simple things and know the OS versions we support as a power user -- but not as well as a sysadmin.
I do find that if I tell them to use ChatGPT to help debug issues, they do almost as well as if a sysadmin or more experienced programmer had picked up the ticket. It gets better troubleshooting, they maybe fix an actual root cause bug in our product code.
maybe our averages are different
