It's interesting to consider that humans are computers made from DNA too.

No idea why people are downvoting you .... it's not like this is a far out statement. People get offended when I just call us "meat computers".

And most of the other top-level comments express the same sentiment as mine but at a later time. It’s definitely not worth trying to understand the whims of HN voting.

We know this is true, because most people can compute that it is 30. The interesting thing is how little dna is required.

This is the furthest thing from the truth. That a human has a certain capability does not in the slightest imply that “DNA”, at least as commonly understood, encodes that capability, at all. A bunch of molecular recipes encoded in a few gigs of nucleotides with some crude feedback loops do not a human make. Quite apart from epigenetics as it’s commonly presented (methylation, and all sorts of histone antics), you mig…

Earlier quoted context omitted.

Every time I hear about a sad story of "this scientist had spent their whole life trying to discover the better computing in DNA and failed" I feel like the reporters are not mentioning the fact that actually the scientist knew perfectly well that their model of computation was inherently unscalable and they were simply pulling money out of absolutely oblivious investors. Oh god I love the _idea_ of better computing.…

At some point it becomes important to ask yourself, "What would I be content spending my life failing to accomplish?" I mean, it'd be nicer to accomplish it, but if you can find something that you could spend fifty years failing at, that on your deathbed you would simply be happy you tried, that's something really special.

Yeah, but it doesn’t mean these people deserve any pity. They actually did something they love. And the fact is they almost certainly knew the risks involved - it’s not like they were jumping into unknown.

I can't wait for the first artificial neural network written in DNA.

I do wonder however whether there exist a deep learning architecture built with real neurons.
