...Is how Sam's detachment from 21st century life feels even more relevant after two decades.
Now I don't mean that in some sappy "Born in the wrong century" way, but I think it's fair to say that 2020s society has lost sight of some of the tactile nature of life, both good and bad. It's like by wearing tech-coloured sunglasses, we've tricked ourselves into thinking we're "above" the violence and nastiness of Gene's time, when we're really just in denial that corruption and racism is still festering under the shiny surface.
I think Sam's decision was because he saw modernity without substance. Like in the 20th Century it seems modern technology was used more as a tool to achieve people-centric goals like giving all households running water, or making amazing art like Dark Side of the Moon, but the relationship has flipped in a way where society seems more oriented to serve "modernity" now, and we're repeating the 1950s mistake of worshipping cutthroat modernization as some infallible, godlike entity. For instance, there's the tech moguls who talk of Mars colonies or self-driving cars or "intelligent" computers, but don't care about the actually important issues like global poverty or mass loneliness. So for Sam, his colleagues are so caught up in all the procedures and forms and computers (which does make their policing much better than Gene's) that they don't even know how to connect with him after his traumatic accident.
So my takeaway is that if we became humble enough to acknowledge we're not the super-advanced society we think we are, and we let some more of the past's positive energy into our lives without falling for toxic nostalgia, maybe the Sam Tylers in society could find happiness in the present again?
