Specifically, he points out that the country is short 600,000 manufacturing workers and 400,000 auto mechanics.
If you think auto mechanics have a bright future you're mistaken. As automakers move to EV platforms cars are becoming much simpler. Both to manufacturer and repair.
An electric vehicle is an order of magnitude simpler in design than an ICE car.
Furthermore, advancements in robotics from AI and—suddenly—vastly cheaper industrial servos will result in fully automated car maintenance. You'll pull your car into a shop that's been pre-programmed for your vehicle and it'll be able to handle 90-99% of all maintenance tasks.
AI only has to be shown—by hand—how to perform an operation once. No matter how many steps! Even if there's all sorts of crazy tolerances where cars can come in different configurations, the AI will be able to find the screw holes and remove panels without damaging wiring harnesses. They can even find screws that drop (which is better than me, haha).
There will always be a need for some mechanics but they're going to mostly be handling big stuff. Not common sedans and trucks.
My prediction: The first fully automated robotics shops will be the tire places. Because there's only so many types of wheels/tires, ya know?
Well, Mr Smartypants, if it weren't for capitalism you would've had to make that chair/table leg yourself so then you'd only have yourself to blame which is the same as having no one to blame!
