Actually this is a good way to find product ideas. I placed a query in Grok to find posts about what people want, similar to this. Then it performs multiple searches on X including embedding search, and suggested people want stuff like tamagotchi, ICQ etc. back.
I feel like these are all great examples of things people think they want. Making a post about it is one thing, actually buying or using a product, I think the majority of nostalgic people will quickly remember why they don't actually want it in their adult life.
I see this a lot in vintage computing. What we want is the feelings we had back then, the context, the growing possibilities, youth, the 90s, whatever. What we get is a semi-working physical object that we can never quite fix enough to relive those experiences. But we keep acquiring and fixing and tinkering anyway hoping this time will be different while our hearts become torn between past and present.
Yeah this is not even faster horses. It's horses that can count like Clever Hans.
