I respect your opinion, but I can't agree.
We're ruining ourselves with ever shorting attention spans and shallow thought patterns thanks to screen addiction. I can find any reason to "fix" a beautiful game to accommodate our downward spiral. Baseball is a game that provides an escape of instant everything and allows us to step back and relax at a different pace.
Honestly, you lost me when you said it isn't a team sport. There is nothing that says team more than an MLB team with good defense. It is 100% ALL about team. Everyone has to know their place and position in any given situation and react in a fraction of a second. If someone doesn't cover their spot it all falls apart.
Defense is important, but that is one player doing his job and covering his section of the field. As far as your views on society's short attention spans, I agree, but that trend is not going away anytime soon. In that sports are entertainment, they need to find their place within the attention economy. I love baseball too much to watch it fade away in the coming decades.
I hear where you are coming from and agree that baseball is at a crossroads. There is definitely an associated risk of both change and inaction. I'm of the opinion that baseball has the most upside by staying as is.
As a society, we will all come to realize what we are doing to ourselves with instant everything all the time. I expect to see a significant pull-back to re-claim our use of time and start checking out of the hectic pace. When that happens, baseball will be there. Unchanged and ready for all. It already serves that purpose for me and many other fans alike.
Changing to accomodate the fickle is a major risk of alienating the devoted core audience.
You have my respect, but people said the same thing before the DH, wild card, and interleague. It's possible to maintain tradition and make a few tweaks to see if they help.
