I don't think the shift has even been that big of a deal for boomers and GenXers. I'm GenX and 5 years go I used to watch cable TV. I would DVR some shows, watch news, etc. And I would occasionally watch a movie or show on Netflix. My DVR started filling up faster than I watched stuff and cable and network news got too frustrating to watch so I just found myself gradually spending more time on Netflix on whatever else I could find on my Amazon Fire Stick. Likewise, while my parents still have cable, I've observed they spend more time on streaming services than watching cable.
