Again, I will never forget the 20-year old kid back in 2014 in my job next to me who didn't know what the hell a Sony Walkman was. Born 1994, the only portable music players we probably knows are iPods. And I have a second cousin who is younger who didn't know what an iPod from an iPhone either! Just like a generation that never saw Michael Jordan and Kobe Bryant play and only aware of LeBron or Steph Curry, there is a current generation that isn't aware of Sony's heyday. They only know Apple's current heyday and aren't aware of their past failures. Kids born in the 2010's may also lose familiarity with Apple someday picking their generation of idols and heroes. Apple becomes old like Big Brother, IBM. The changing of the guard.
Yup times always change. I was an Aiwa person back in the day, it had more features than Sony Walkmans.
