Toto, the Japanese company that manufactures the most technologically sophisticated toilets on Earth, has pushed humanity further into a plumbing utopia. This flushable toilet (with a built-in bidet!) can be carried around and re-positioned as needed.
The obvious next steps would be make the toilet a tracked vehicle and give it rudimentary artificial intelligence.
The company representative in the video below seems to think that this invention should be marketed to hospitals and care facilities, but I'm at a loss to understand why the company wouldn't aim at a general consumer market.
