Agreed, I do believe eSports and physical sports can coexist and will probably do that for the foreseeable future. With PEDs you have the ethical discussion of the harm done to the body and some using it and some not (I do think there's a lot of pro's taking it on cycle that we haven't found out about) but with the exoskeleton it could possibly prevent injuries and increase spectacle and at the same time it's fair since nobody can hide it (at least for now) they'd just need a separate league.
Good point on the elderly, might actually be worth living longer with increased mobility
