Brains on Loan

Instantaneously, your brain power increases by an order of magnitude. Previously difficult problems are now trivial. Tip-of-the-tongue moments are a thing of the past. All manner of intellectual and creative pursuits are at your fingertips.

This is the new reality with the Brain Cloud.

When brain-computer interfaces are the new normal, we’ll prosper from the selective advantages of both silicon and biology.

Think of the electrical grid. If I install solar panels outside my house that provide more energy than I need, that energy flows back into the grid. Then, I’m provided an energy credit toward my next bill. I’ve made the investment in something that society can harness, and I’m repaid for that investment.

Take another example: SETI@home allows you to loan out the processing power of your computer to analyze data for the Search for Extraterrestrial Intelligence. When you’re not using the computer, it’s still providing something useful to society.

Enter the Brain Cloud. When I’m asleep, let’s say, I’ll be able to loan a portion my brain’s processing power to the grid through a brain-computer interface. I can do this because much of my brain is actually a back-up system, a sort of biological insurance policy. Case studies have shown that some individuals are born with only half a brain, only portions of their cortex, or no cerebellum at all. Yet, astonishingly, they lead relatively normal lives.

Of course, the beauty of the Brain Cloud is that no one has to permanently give up portions of their brain. Instead, processing power is out on loan only temporarily.

At this point, a reasonable person might be wondering: Why would I do that?

Just like with the electrical grid, there’s much to be gained. Each time I put my brain on loan, a portion of the processing power I lend out will be used to mine for cryptocurrency through a blockchain. I’ll receive compensation for putting processing power in the grid, and others will be able to harness that power when they need it.

The blockchain will serve another purpose. It will keep an exact, private, and non-refutable ledger of how much processing power I’ve loaned. While anyone will be able to observe that a transaction occurred in the blockchain, no party will have access to the contents of that transaction – allowing me to keep the contents of my brain private.

We are all perpetually hamstrung by our lack of brain power. Yet, for the processing they do, brains are fantastically efficient. Processing in computers, on the other hand, requires massive amounts of energy. Most of this energy ends up as heat, rather than the actual computational processes we want in the first place.

By moving processing power through a brain-computer interface grid, we would be selecting for the best of both worlds: super-efficient conduction of signal through machines, and super-efficient processing of signal through brains.

It’s a win-win.
