The next step has already started.
Micronizing truely massive supercomputers is the next step for "applied sciences". We've gotten used to measuring data centres in power, I recon it will be computing power per cubic foot or something like that. It'll start with drones, then it will move to shipping and long haul robotics. After that it'll move to mining applications. I'm not talking about automating but rather truly autonomous applications that require massive computation for collision avoidance and programmed execution.
At this point it'll be a race to redo the industrial age, albeit with micronized robotics. Again, already started with 3D printing.
Hopefully by then someone figures out how to get off this rock.
