Prediction: probably sooner than later, you'll switch to pickleball (due to peer pressure, curiosity), and when you do, you'll be reluctant to ever go back to tennis. Pickleball is the real dill, you know.
At least on the youth level, tennis won't totally disappear like adult fast-pitch softball.
There will always be little girls who want to be the next Serena and little boys who yearn to be the next McEnroe.
But pro pickleball has arrived .... videos are all over YouTube. And if you check it out, you'll see mostly younger people playing.
