I don't use or pay attention to any of that stuff. I just use Strava to track my rides. I don't share anything and I don't want anyone to know anything about me, certainly not on Strava, an application that tracks your location.
For folks that do participate in all of that, good for them. The fact that there are errors in Strava's data, well, garbage in, garbage out. If they can leverage AI to clean up their data set, good for them.
I guess if one participates in all of that, then it's important that the data be accurate; however, we live in an imperfect world and AI ain't gonna fix that.
