We interrupt this "GET OFF MY LAWN!" segment to bring you back to reality.
First, regarding the pitch clock ... the reason why the experimental pitch clock in AA and AAA didn't result in a lasting reduction in game time was they included a loophole where a pitcher could step off the mound and reset the pitch clock. Once pitchers figured out how to work the system, things got slow again. They implemented a pitch clock again recently in A ball, and closed the loophole, and it dropped average game time by 21 minutes. And it's not just the overall game time ... it's the down time in between events that matters. Get in the box and hit. Get on the rubber and pitch. Stop fiddling with this and diddling with that. Youth (with decent talent)/HS games are often more enjoyable to watch than pro games, because of this much better pace and flow.
Second, regarding pitchers that can actually pitch. That's just flat-out bunk. The last 5 years, BB/G have hovered between 3.23 and 3.39 (the COVID season when pitchers weren't as prepared). If you remove that outlier year, the range was between 3.23 and 3.27. Most 5 year ranges won't be much different. Actually the 5 years prior to these last 5 had the lowest BB/G rates since the mid-60's ... and they were decently to substantially higher BEFORE the mid-60's.
Pitchers are, historically speaking, REALLY FREAKING GOOD right now. The amount of advanced training, using data capture and analysis, and physical training, is CRAZY. They've learned how to throw the ball really friggin hard and, more importantly, how to control velo and spin rate/efficiency to the point where these pitches they're throwing are just phenomenal. 4-seam fastball usage is actually down, despite the overall velocity uptick, because they can now throw cutters, 2-seams, sinkers, and all sorts of variants just by adjusting finger location, grip pressure and wrist presets, and these pitches are faster than 4 seam fastballs used to be ... and the movement on these things is unreal.
This may result in a more boring game than the traditionalists would like, but pitching has taken a HUGE leap forward. Hitting has struggled to keep up (and it's not because of these crazy "launch angle swings").
Third, the youth simply can process information faster than previous generations, because they've had so much thrown at them, via technology. Things can keep their attention as long as they're interesting.
