As a kid I just remember being enthralled by what the future would bring, and you'd see tons of writing prognosticating about things like "cities of the future" and "houses of the future". I think the fundamental change is that all of those were filled with a sort of techno-optimism. Now, though, I think there is a widespread feeling that tech, as a whole, is no longer in service to the improvement of human society. It just feels like it went off the rails in the past 15-20 years or so, where for a lot of us tech feels like it's made our lives worse.
I no longer look forward to the newest tech or gadget. If anything, I look forward to going for a walk in the woods and leaving my phone at home.
When we imagined computers, we imagined unbounded access to knowledge. Instead, we got an internet drowned in corporate slop, constant surveillance and unrelenting attempts to destroy privacy.
When we imagined cars of the future, we imagined beautiful, affordable, eco-friendly vehicles. Instead, we got products centered around inserting new subscription fees into the model of car ownership.
When we imagined housing of the future, we imagined gorgeous futuristic architecture for the family. Instead we got an unaffordable investment market designed to siphon money out of the common person.
When we imagined AI, we imagined being freed from menial work, free to pursue art. Instead we got corporate push to replace artists and writers with dysfunctional content generators built on stolen data to save a few cents on the dollar.
When we imagined technology as a whole, we imagined something that would empower and better humanity. Instead all we got was a tool the rich use to exploit the rest of the world even harder with no limit.
