It's probably going to be like with AI. People talk about it for years and nothing substantial happens and then suddenly it takes off. I was working on AI around 2005 (we called it neural networks). There were no good libraries, the literature was difficult to understand and nothing really worked (at least I didn't get it to work). I was still a student and pretty disillusioned by the whole idea. A few years later the field took off and now it is ubiquitous.
I don't know, it seems like AI/ML are on the cusp of the "Trough of Disillusionment" themselves. And they've been talking about Graphene, Nano-tech since I was in high school.
it just stopped being AI. night mode camera on recent android and iphones were top of the line AI couple years ago. DLSS (deep learning super sampling) is allegedly borderline magic; it'll just be DLSS sometime next year. google translate and alpha zero are most definitely amazing AI.
