A wheelchair can be much better than nothing and still be far inferior to a potential exoskeleton. I use a wheelchair whenever I leave the house, and I am not a fan. There are so many places I cannot go: anywhere that requires stairs, the beach and most other places that are unpaved, anywhere without curb cuts, any foreign country that doesn’t have accessibility laws, anywhere with a hill that’s even a little bit steep. I would happily pay $100k for a really great exoskeleton (if what’s in my imagination could be made real, anyway).
