> Reminds me of how things start off as entertainment many times, and eventually make a way into an industrial application. I was just thinking about this phenomenon, in terms of how it runs counter to the criticism of "solutions in search of problems" and projects derided as "toys". This is a good response to those condemnations: often great ideas work in entertainment first, then industry. The canonical example from antiquity is Heron of Alexandria's automata. Nowadays, roller coasters seem like a technology that future historians will puzzle over non-utilization beyond entertainment. (The cause of course is zoning, which halted housing and transportation innovation a hundred years ago.)
