It might be due to a combination of a few things:
1. The compounding acceleration of tech has numbed us to the marvels that are happening around us.
2. Big Tech, and Capitalism in general, has been getting more and more extractive than innovative for a long time, which has made us cynical. (Or maybe it's always been like this, we just notice it more as we age.)
3. New form factors excite us more than new capabilites because they're much more tangible. Things like CRISPR and GLP-1 are basically miracles but don't impact our day-to-day, whereas the iPhone revolutionized how we interact with the world on a daily basis.
4. Movies and TV have portrayed science fiction and futuristic technology so convincingly for so long, that when those things actually come true we don't really notice.
I think these explain what's happening with the current AI revolution. The technology, if you think about it, is objectively insane. It fills me with excitement and dread.
However we've seen countless variations of AI in popular media for decades so it doesn't seem "new." Worse, GenAI was introduced to us as a chatbot, a form-factor even more underwhelming than the mostly useless Siri and Alexa, let alone humanoid robots or holograms. And to top it off, it's threatening to take our jobs, something that popular SciFi didn't really talk about, so already we are primed to look at it more negatively.
But I cannot overstate how impossible it was just 4 short years ago for computers to do any of what they are doing today, and how much it will change the world. And yet look at the discourse around it.
It's like some weird, alien life has suddenly sprung up amongst us and we're all just going, "But it writes crappy code though."
