I'm also glad folks are tinkering. That said, bike tires are probably not where I would expect something like this to land. I would love these to replace the tires on things like utility carts, air compressors, etc that typically end up with solid tires. Those solid tires are awful, but pneumatic ones must be filled and that's annoying for infrequently used stuff.
Agreed. I happen to enjoy the hobby of tinkering with old bikes, so my bikes are typically a few decades behind the latest technology. So I can adopt a wait-and-see philosophy.
But still I remember a cynical comment by my dad, maybe 40 years ago. They had just announced some new advanced material, and my dad said: "Mark my words, the first applications will be high end bikes and golf clubs." Also, improving on the bicycle is a very common capstone project for design students.
