To take a simple example: I grew up with computer games in the '80s where there were no 'physics engines' or frameworks for building games. As a result, each game was an expression of the author's personality somehow. Fast forward to the noughties, games bored me as they mostly looked and felt the same, or maybe felt like 3-5 different games all packaged differently.
Another example: going abroad on holiday in Europe (I'm from London) used to be a relatively wild, vibrant experience, filled with unexpected differences and challenges (not all positive). There were no McDonalds or Starbucks and the shops were filled with unfamiliar products and foods. Now everywhere in Europe feels the same when I visit, especially with smartphone in hand.
And films went from wildly different to one another to what now feels like 'arty' and 'CGI' being the two choices.
