You can still find phonograph players and amps with phono inputs in thrift stores. You can spend lots of money getting a high end system from an audio shop too. How long that will last is impossible to say.

Phonographs records are amazingly durable. My mom's 45s received no special attention for 30 years, boxed up in a New Orleans attic. It got hot up there and one or two were ruined, but almost all of them could be made to play. Sometimes that took some work, but they played. Yes, that's a 1kg chunk of brass sitting on top of a cup making that 45 lay flat. I also used up to 10 grams to weight the needle without adjusting it's balance. Though I intend to keep my records as well as I can, I don't think my children will be able to find a working player.
