Several years ago, I was a mentor at a weekend hackathon for teenage nerds. At the end, the kids presented their results to a crowd of mostly their families and some local newspaper journalists.
One of the kids, performing on stage in stereotypical "dangerous hacker" hoodie outfit, presented a prototype of a "secure encrypted, censorship-free chat system". It actually was a a non-functional click dummy based on an existing webchat demo project.
The kid spoke about features of the chat system that did not exist, some of the promised features were impossible to implement.
It was all vaporware.
The audience was vowed by the genius dangerous hacker kid and applauded. It all sounded so plausible to them.
In the age of vibe-coding, this is an experience I often think back of.
