You should ask yourself this, not me, you're the one who blindly believes what Musk says. He also said he was creating a new political party in the US, how's that going? Did you believe him when he talked about landing people on Mars in 2018? It’s 2026. How is boring company going? etc. I think you're overinterpreting what I wrote and projecting. I'm telling you how the physics works, and the physics is simple here: unless you change the physics or discover some exotic, cheap materials, this is 100% not economically viable today or in the near future.

Because "investors" are a large group. Many of them are not involved in the industry and are clueless about tech. Same reason they invest in OpenAI, that hasn't made any money.

Investors, both commercial and individual, often have more money than sense.
