Lol. No, its more like everybody will line up take care of those more important things when they get access to a time machine, but when I get access to a time machine, I want to take care of my pet peeve :)
While you're back there, convince people to do IP truncation rather than fragmentation. Truncation would probably be a lot more useful at lower cost than fragmentation, and maybe path MTU problems wouldn't still be an issue. *grumble*grumble*
If you have a gigabit internet connection, then most of the value of 10G comes from data sharing within the intranet, which just never caught on outside of hobbyists. And a 1G switch can still handle a lot of that, You don’t even need 10G for LAN parties, and whether backups can go faster depends on the storage speed and whether you actually care. Background backups hide a lot of sins.
I’m hoping a swing back to on-prem servers will justify higher throughput, but that still may not be the case. You need something big to get people to upgrade aging infrastructure. What would be enough to get people to pay for new cable runs? 20Gb? 40?
If you become a programmer / sw eng because you love it, i.e., building software or tinkering with teh, you'll be fine. AI will just be another tool. And tour career building won't feel like hard work. You are going to have a blast.
If you do it to have a high paying career, just don't. There are already too many people of that type in the industry. Any colleague who got into it for the money (or 'stable career') is usually much less fun to work with.
