Tesla Roadster demo wows, then the shipping date cools the room

The Tesla Roadster livestream (50112657) split the thread. One commenter called it possibly the most phenomenal tech demo they had ever watched, and credited the engineers behind the stunts. The sharper reply called it a big nothingburger: production starts in 2028, and what was shown is a jumping car, not a flying car, so who actually wants it?

The same argument shows up in a smaller form around Ultramarine, DeepSeek and the StarCraft agent. A strong demo or chart earns attention, but readers immediately ask what ships, when, and who it is for.

The nuance: even skeptics admit the engineering is impressive. The argument is about whether the demo is a product.
