What does 10x more capable look like now? Surely at some point we will reach an asymptote of what can be done purely digitally: all useful coding tasks can be automated, most math research, etc. At some point the physical world becomes the dyke holding back the singularity; until these genius models can scale their investigation into physical experiments and manufacturing, the future will have arrived only in the digital world.
I think you're making a mistake in thinking the digital world is the only one reachable to AI. Robotics and sensing would be opened up by a sufficiently capable AI.
Yes, this is definitely more an article about Cyan than it is about the Myst-like genre of games. Quern was relatively popular and it is certainly the best Myst game since Riven. Dimhaven is quite good too if a lot more linear. I think the problem is that it’s just very hard to build a satisfying puzzle game. You need brilliant puzzles and a lot of testing.
