I'm also a skeptic on AI replacing many human jobs anytime soon. It's mostly going to assist, accelerate or amplify humans in completing work better or faster. That's the typical historical technology cycle where better tech makes work more efficient. Eventually that does allow the same work to be done with less people, like a better IP telephony system enabling a 90 person call center to handle the same call volume that previously required 100 people. But designing, manufacturing, selling, installing and supporting the new IP phone system also creates at least 10 new jobs.
So far the only significant human replacement I'm seeing AI enable is in low-end, entry level work. For example, fulfilling "gig work" for Fiverr like spending an hour or two whipping up a relatively low-quality graphic logo or other basic design work for $20. This is largely done at home by entry-level graphic design students in second-world locales like the Philippines or rural India. A good graphical AI can (and is) taking some of this work from the humans doing it. Although it's not even a big impact yet, primarily because for non-technical customers, the Fiverr workflow can still be easier or more comfortable than figuring out which AI tool to use and how to get what they really want from it.
The point is that this Fiverr piece-meal gig work is the lowest paying, least desirable work in graphic design. No one doing it wants to still be doing it a year or two from now. It's the Mcdonald's counter of their industry. They all aspire to higher skill, higher paying design jobs. They're only doing Fiverr gig work because they don't yet have a degree, enough resume credits or decent portfolio examples. Much like steam-powered bulldozers and pile drivers displaced pick axe swinging humans digging railroad tunnels in the 1800s, the new technology is displacing some of the least-desirable, lowest-paying jobs first. I don't yet see any clear reason this well-established 200+ year trend will be fundamentally different this time. And history is littered with those who predicted "but this time it'll be different."
I've read the scenarios which predict that AI will eventually be able to fundamentally and repeatedly self-improve autonomously, at scale and without limit. I do think AI will continue to improve but, like many others, I find the "self-improve" step to be a huge and unevidenced leap of faith. So, I don't think it's likely, for reasons I won't enumerate here because domain experts far smarter than I am have already written extensively about them.
