Music maybe but surely not sports, science and so on...
Nowadays most successful musicians can't even play an instrument but that doesn't mean that they are idiots or something. Just that we have new possibilities nowadays to make music people in the past simply didn't have. Who knows which kind of music the exact same The Beatles would make if they would be young now.
But I agree that I think music felt "More real" in the past.
We have a lot of geniuses nowadays especially in science and other important areas. It's just that you didn't have so many in the past that we still talk about those who were so great for their time. For one smart dude from 1920 you have 100 nowadays so that you will simply know that one single dude from 1920 better because he was simply the only one then^^
TV it depends. I find some TV shows nowadays just awesome and better than everything from the past (Game of Thrones as example) but for movies I find the past better but that doesn't mean that in 5 years it can't be great again.
Sports is kinda like with scientists. You just have more nowadays and with that it's harder to let someone reach the status of Ali. That doesn't mean that Ali would even have a chance nowadays just because we know him so good. Not so many standing out from the others in their sport doesn't mean that we don't have great ones. The best ones are just closer to each other maybe with all the training perfectly thought-out on a scientific basis where the best train pretty much all the same while in the past there was no scientific evidence that you should train this and that so many hours to reach your best form and it was all more about feeling instead of facts how to train.
Nowadays you see people in sport doing exactly what some data from a computer tells them. That may look more boring on the TV screen but that doesn't mean that they are wore.
