Maybe this whole "emitting body waste into a liquid" thing isn't a good idea. Maybe vacuum containers should be held to one's body during emissions and the silver/copper/stainless steel interfaces cleaned with lasers and UV afterward. The toilet was a great innovation in its day, but it seems ripe for disruption.
And think of how much more productive we could be if we could save trips to a dedicated room for it! Every desk could be fitted with a waste vacuum, right next to the soylent dispenser. Just don't mix them up...
That is a bit overkill and lacking in energy efficiency and sustainability, though. A more environmentally conscious solution would be for western nations to bring back some French innovations from the centuries ago such as the bidet followed by the trebuchet.
This post looks grey from downvote, but I agree, I am profoundly disatisfied with how stagnant flushing technology has been. I don't just want nice bidet and warm seats, I want a continuous flow removing poop while I'm on the seat.
