One should *learn* to drive/ride without any aids, true. My fun "collectionist" car doesn't have ABS or traction control, and I love driving it. But it is also 115HP (but the car is very light), so while pretty spirited it is easy to drive (gets a bit tricky in the rain though, but I avoid driving it in the rain).
But now, all my motorcycles have ABS, I view that as a great safety feature. It's awesome in the rain or when riding over greasy roads and wet autumn leaves etc etc. 1 of them has traction control, but I leave it in sports mode with minimal intervention, and afaik it has never engaged. I also had one bike with tracttion control that acted up in light rain and nearly high sided me into geostationary orbit.
As to traction control, yeah, I kinda detest it because it allows everybody to drive/ride a 500HP car or 200HP motorcycle. Safer for everybody, yes. But as has been discussed, it ruins many things. And without traction control the vast majority of people would brain themselves on such vehicles.
When I still lived in Germany (as a young engineer), I had a BMW 318is that had 140HP, which sounds like nothing these days, but without traction control in the snow or heavy rain it could be a bit of a handful at times, and I spun it out 2 or 3 times, luckily without any damage other than to my pride.
My favorite car ever (other than the 356 replica and possibly the Abarth 500), was a 1995 Jag XJS I bought used (~1998 pic below). "Only" 240HP, but zero traction control, could also get quite "interesting" in rainy conditions on highway onramps, plenty "serpentine moments" but never an accident. (Tragically my ex wife forced me to sell it, as she claimed it showed I didn't want kids... we never had kids despite trying hard). I miss that car.
