Public roads aren’t really a sporting arena, so probably actual sports use will continue in an appropriate venue.
Certainly there's a lot of skill to riding a motorcycle that TCS/ABS/Slippers (and displacement!) do not replace. I love that aspect of motorcycles. It's pretty amazing to be riding at your peak performance in B group on the track on a 650 and have someone on a Ninja 300 blow by you on an inside line at 20-30 seconds faster pace than you.
Unfortunately I think both those are inevitable. For now I'll keep riding my 15-year old carburetor bike with no rider aids.
Speaking of rider aids, I sometimes wonder where the balance is between safety and fun. I think the sport is only interesting if it's challenging, so a self driving motorcycle doesn't seem like it's good for anything other than transportation. What about TCS? ABS? Slipper clutches?
