When it comes to technology the interesting things will come when they augment the human body. Imagine a person who can run 50 or maybe 100 miles per hour. All past records would become completely meaningless when such nano-tech and robotic additions exist.
I don't know whether the "average" guy will be able to get the "Johnny Bionic Commando Kit" at the local sporting goods story, then nobody will watch athletics.
But what becomes of a collision sport like football in general? Because ain't nothin' in smart tech. that will make a 100-mph collision easily survivable. Whole different tech. All AI can do is train a robot to avoid the collision - and as we're seeing with cars, telling you and having you avoid it is way slower than just avoiding it itself, once it knows how to.
As for saying it will never be added to the game that is likely untrue. People will not tune in to see athletes doing things well below what they can do with such upgrades which will be common.
For the read augmentation, hard-core fans would pay for the feed so they can see what a QB sees, or some subset... and we'll all
know that the QB in question did/did not respond quickly and accurately to the outputs in the visor.
Good point in general though... just because it's impossible to augment football players while keeping them alive (e.g., to run 100 mph,) doesn't mean that people won't be able to augment
themselves. If/when we get to that point, football will be the
only place where the augmentation would be missing. Then the only real solution will be to remove the soft squishy human athlete.
Which sucks, because BattleBots is already a show.
I hope there's, say, 20 more years left in the game. If I'm still alive after 20, I hope I'm crotchety enough not to care after that.
