We may be showing our age.
When I talk to younger people about the Beatles and the Stones (I used to teach guitar for years), some of the kids prefer newer bands I have almost no knowledge about.
While I love the Beatles, bands that got that type of reaction from me were mostly from the 1970s like Pink Floyd, the Eagles, and of course solo material from former Beatles. A couple exceptions of artists or bands I really liked after 1980 who had legendary releases have been U2, Michael Jackson, Nirvana, and just a few others. Classic rock and soul do it for me most of the time and I tend towards Detroit and the British Invasion, thank you.
While I know a lot of music critics like Oasis, and have drawn comparisons to the Beatles, I just never got on the Oasis train. But recently I saw a youtube on Tomorrow Never Knows done by Oasis and they were incredible. Another band from that period I really need to listen to is Radiohead.
For new bands, I can't think of any, long term, who will be as relevant as the Beatles. I put the Beatles on a short list (from the first two decades of rock and roll) with Chuck Berry, Elvis, the Stones, Diana Ross, the Temptations, and the Beach Boys. But as time moves forward, and people's tastes change, the Beatles will be a largely unknown band when I sing their praises.
My dad and his generation used to rave about Sinatra, Glenn Miller, Benny Goodman, and Billie Holiday and how their music would be remembered forever and overshadow this rock and roll I liked. It wasn't until many years later did I realize that those classic acts of the '30s and '40s were as good, if not or better, than anything I ever worshiped in the rock and roll genre.
It's all relative and all I really care about is that I liked the Beatles and I won't waste my time trying to turn a new generation onto them if they are intent on Lady Gaga, Justin Bieber, the Jonas Brothers, or some death metal act who all sound the same to me.
