I walked into the restroom. A mechanic stood at the sink fixing something. It saw him holding a toilet seat. He was fooling around with the wiring of the apparatus. Then he replaced some electronics components and rewired the seat.

Toilet sensors

It never occurred to me that even toilets could be usefully equipped with electronic features. I asked the mechanic. He explained that the toilets in the building are all connected to the Internet. If there is something wrong with the antiseptic fluid produced by the toilet, it starts calling out for help. He told me that the towel dispenser was also connected to the Internet, so that when it runs out, a maintenance operator is called in. Makes sense.

Never has technology so much helped improve the The Loo.

To cell sensors

So all things will be supplied with sensors. And it looks like these sensorized things are getting smaller and smaller and a reaching the nano space.

Sensors are gtheetting so small that they can flow through our blood and mend our bodies. And maybe fix cancer cells in the future. Or detect issues with blood vessels. Or measure the chemistry in our bodies. They can be injected in plants to protect themselves from diseases. Or be used in constructions to measure stability at smaller scales than we had ever assumed possible. Possibilities beyond imagination.

Neb sensors surveilling the body 

Imagine what it would mean if we could instrument every cell we like to. I would like a surveillance team of bot swimming through my body, like the Nebuchadnezzar in the Matrix flows through the sewers and tunnels of the abandoned cities.

To signal when my internals run out of supplies.
