The problem with gearheads is that they can displace their passion for the activity itself onto the gear around the activity...and get better at having gear but not get better at the activity.

E.g., guitarists who own 80 of the same guitar and spend many hours on the internet arguing about tiny variations in what Fender was doing in 1961. And then they put out a video and it turns out they can barely play guitar at all.

I wouldn't exactly criticize them for that choice, but it's definitely a choice. Or maybe not a conscious choice, because the road to improvement is hard, but the road to more gear is loaded with honeypots of dopamine.
