Elon Musk Has Some Bad thoughts for Mass Transit.

Tell what you will about Elon Musk, but the man has thoughts. Loads of them.

He has concepts about how to enhance Twitter and colonizes Mars

He has concepts about space tourism and the future of artificial intelligence.

He has thoughts about how to end the war in Ukraine and save children captured in underground caves.

Adam Kovacs, a popular YouTube creator, suggests that unyielding bravado and huge wealth don’t necessarily change bad ideas well.

Mr. Kovacs, who has created a large following for his criticisms of faulty urban planning and design, takes a close look at Mr. Musk’s proposals to recast mass transit: the Hyperloop and the Boring Loop.

Both concepts have created much eagerness and even assets, but as Mr. Kovacs explains, they are unessential complex and not created for real people.

There’s even a word for exciting but awfully flawed concepts like this: “gadgetbahn.”

Mr. Musk, he says, “would rather inject millions of dollars into some made-up tech fancy than doing something literally useful for us mortals.”
