Knowing that our brain uses just about a few watts of power and is as powerful as a supercomputer using megaWatts of power in 2016 and that we seem close to the physical limit of what silicon can do in terms of energy efficiency (we would need to increase efficiency more than a million times to reach organic levels of energy efficiency), I was wondering if silicon has a chance to ever be more efficient than some sort of organic computer.
Let s say we reach the physical limits in CPU lithography. Would the perf/watt of silicon still be worse than that of our neurons?
If we managed to synthetically produce some neurons and control them like we control current transistors, we could just produce massive amounts and create some sort of giant organic megabrain. Wouldn't that kind of organic computer be more powerful than any silicon based computer?
The same question applies to data. Does DNA have a much higher density and energy efficiency than silicon?
I m not an expert in those fields so I might be completely wrong!
