Thank you for that. It made me chuckle!
Here are some counter-examples:
* A new car company making a new kind of vehicle. The first time I heard he wanted to build a new car company that would sell EVs, I dismissed it as crazy. Tesla now sells close to 2M vehicles a year, roughly comparable to BMW.
* A new network of EV charging stations. The first time I heard about it I thought the company would never recoup the capital cost.
* A new rocket company. The first time I heard about SpaceX's early days I dismissed it as crazy. SpaceX now sends 10x more cargo to orbit than everyone else, public and private, combined.
* A new satellite-Internet service. Prior to Starlink, every previous attempt to offer cheap and reliable Internet service via satellite had gone bankrupt.
* A new brain-machine interface. The first time I heard about Neuralink I dismissed it as "way too early." The company just showed a disabled man using a computer with his thoughts.
* The latest beta version of the self-driving software (FSD Beta >= 12.3.6). I've tested it and I am... impressed. Even though it happened much later than Musk predicted. Here's what it's like: https://www.youtube.com/watch?v=eIjOs1Gum2M
* Dojo, which is now online. There's a picture of it on the last quarterly deck: https://digitalassets.tesla.com/tesla-contents/image/upload/... -- though I don't know if it will be able to keep up with Nvidia's offerings, which are always improving.
Some things you mention failed, and the jury is still out on Cybertruck, Roadster, Solar Roof, and X (Twitter).
But the track record is there.
