I can't help but agree with this, at least a little.
However, the polished nature of the holds and the funky cracks just make it more "interesting". The climbing is harder than when I was a kid (due to 20 years of polishing), but I'm climbing harder too. I suspect many (most?) climbers are in a similar situation. The only people really losing out are rookies and today's generation of sneaker wearing kids.
No doubt the millions of people who've used the UW rock far exceeded the original expectations (and maybe even intentions). Also, the centerpiece "highball of death" is lightly used at best. The UW rock is cool, but a lot of lessons were learned from it that went into Marymoore Park. Schurman Rock, the true OG training rock, is still totally visionary and other than size is better than basically every climbing structure that has been built in the last 80 years. I would like to see the original preserved as much as possible, but maybe this is a good time to talk about an expansion of the facility. However, in defense of the UW rock: it has a far better singles scene than any other local climbing rock.
