The obvious difference is that AI has abundant use-cases, while Crypto only has tenuous ones.
Maybe there is added negativity considering it is a technology where there is clearly a potential threat to jobs on a personal level (e.g. lift operators were very negative towards automatic lifts).
Copilot to be another.
Midjourney to be another - or at least diffusion based image editing tools which can be brought into photo and video editing workflows. The killer app here is probably integration of diffusion models into apps like Photoshop (and eventually video).
Some real virtual assistant applications seem right around the corner (i.e. a real life J.A.R.V.I.S seems like an inevitability within the year rather than a pipe dream, and to me would be a killer app)
And then lots of other killer apps are pretty obvious to imagine with development (e.g. customer service applications like IT helpdesks, Computer game dialogue where you can really influence interactions...)
As always, the tech isn't the problem - the way business applies it is. Customer service automation isn't done to help you better - it's done to make it cheaper to make you go away without making too big of a fuss. Companies building and employing customer service systems will find ways to make even GPT-4 incapable of providing anything the customer would find remotely useful.
