I agree completely with your synopsis, but I'm still a bit torn on whether it is a bad thing... I first golfed using my parent's 1970s era wood headed, aluminum shaft clubs that were extremely limited - it really was entirely about the golfer, not the equipment. Years later when I picked the game back up a bit - it's clear the equipment is doing a lot of work to make the user better. That said, at least at the amateur level - most of us still aren't great golfers, and given that many golfers are older and have physical limitations, it is a bad thing if better equipment improves their game and potentially gives them a few more years of enjoyment over the old stuff?
I have a parallel view on skis - man those old straight long skis were hard on knees and so many skiers were lucky to still be charging after 40. Lotta knee surgeons made good money in the 80s! Then along came parabolic skis and made us all better and safer skiers - almost anyone can shred in today's skis because they are frankly easy to ride. In that case - the technology was a positive innovation.
Your last paragraph nails it - the magic of baseball is its simplicity. Baseball games should take a long time and be an act of leisure. The idea of putting a baserunner on third to speed up a game is an abomination in the same way the addition of something other than a wood bat would detract from the skill of the player swinging it. So I'm with you - this could be some kind of equipment arms race that won't end well.
