I didn't understand the comment to be about specific products, but more overall categories. I think space tourism is likely going to be a huge category, it's just decades away still. I don't know about supersonic passenger flight or building tunnels everywhere. It may never be worth it for those categories. But regardless, I don't think that many people really thought Musk was going to build much with Boring. I certainly didn't. And has anyone in the last three decades (other than Boom's hapless investors) thought that supersonic passenger flight was going to be huge?
