alt Hacker NewsI always remind myself and everyone else that human DNA is "only" 1.6 GB of data, and yet it encodes all of the complex systems of the human body including the brain, and can replicate itself. Our intuitive feel of how much stuff can be packed into how many bits are probably way off from the true limits of physics.

That's not strictly true - DNA doesnt replicate itself, a cell with DNA replicates itself.
You need to count the information contained in the non-DNA part of the cell too.
Just in case it's not obvious, you can't take human DNA and put it in a cat cell, it won't work, that cell won't replicate.

And anybody who’s ever met a baby can tell you, they score very poorly on most llm benchmarks.
Human DNA has 3.2 billion base pairs, and with 2x the information density compared to binary systems (due to 4-letters as opposed 2), that's roughly 800MB of informational data.
Second, what's even more crazy is that roughly 98% of that DNA is actually non-coding.. just junk.
So, we are talking about encoding entirety of the logic to construct a human body in just around 16MB of data!!!
That's some crazy levels of recursive compression.. maybe it's embedding "varying" parsing logic, mixed with data, along the chain.
