Longer term, automation will increasingly replace jobs for less well trained workers and that will be an issue.
I work in heavy industry - big trucks, cranes, noisy machinery, welding, mining, structures, ship-fitting, etc - and one thing that's very apparent, if not worrisome, is how hands-on mechanical aptitude will be thoroughly erroded once the 50s/60s are no longer on the job.
Take the construction and maintenance of a long-haul, pressured piping system for instance. Operations of all mechanical equipment is primarily operated by automation: charging pumps, valves, strainers, purifiers, heaters/chillers. The 20s/30s can naturally interpret the entire system through automation screens. If a pump goes offline it's not hard for them to make up for it by finding other pumps to bring online and orient flow by automation screens.
What worries me is when specific equipment requires onsite, hands-on repair. You're hard pressed to find anybody under 40 with natural instincts for taking apart, diagnosing for repair, and reassembling pumps, valves, etc. When it comes to my work I'm very thankful for my coworkers in their 50s/60s (many are Navy vets) who can be left to the greasier, hands-on side of the job.
Goes to show you how a generation (Millenial & Z) of playing video games and bitching about Star Wars (while out in the garage Dad and Grandpa (X & Boomer) fixed the lawnmower motor themselves) is quite the foreshadowing to what can be expected of differing technical aptitudes going forward.
