Yes, and definitely...no. I've seen a few self-taught engineers. They usually start out as draftsmen and never quite understand the subtleties of mechanical stress and fatigue design. They don't have the training.
I'm not really keen on going to a surgeon who doesn't have some impressive papers hanging on his wall. The guy that cut into me trained at Johns Hopkins, for example. Medicine isn't really something that can be self-taught, except on the simplest levels.
The problem is not the system so much as how the system has been corrupted by barbarians and thugs who seek intergenerational power by lying to children and turning them into unconscious traitors against their family, their culture, their country and even their race.

It's an opinion Forum, so fair enough Sled; yet my bias remains w/the past.
Consider the Great Pyramid at Giza, a moment.
It's some 500 feet high and contains 2.3 million blocks of stone in its structure.
As such, each stone block weighs some 5,000 pounds.
Four thousand years ago, none of the modern tools/techniques available to us
were available to the Egyptians!
So how did they manage to get 2.3 million blocks weighing 5,000 pounds each
in place in order to construct the Great Pyramid???
The Greeks and Romans produced similar feats even more breathtaking architecturally.
Further the Cathedrals that Europe produced during Scholasticism are beyond
breathtaking, all the way to the Renaissance.
My point, plain and simple is: WE AIN'T THE GREATEST ANYTHING!!!
Anyway stay well.
