Nobody did it before.

Before he proved it was profitable. BTW, every business venture I started was considered crazy by my peers.

Musk was an early investor in AI.

The Boring Company is successful. It has found a profitable market boring holes for infrastructure cables and pipes.

People said him buying Twitter was crazy. Oops! (What annoyed me about that was I had some Twitter stock, and it was forcibly sold to Musk. I wanted X stock instead! Alas, it is private.)

I put my money where my mouth is. I've invested in TSLA and am a happy shareholder.

There is a long list of crazy ideas that businessmen took on, that became so successful everyone later thinks that those ideas were obvious.

Such as an internet phone. Like a personal computer. Like a Xerox copier. Like jet engines. Like a pencil with an eraser on the other end. Like interchangeable parts. Like the circular saw. Like electric power utilities.
