White Hat Guy: Biology is largely solved. DNA is the source code for our bodies. Now that gene sequencing is easy, we just have to read it.
Person 2: It's not just "source code". There's a ton of feedback and external processing.
Person 2: But even if it were, DNA is the result of the most aggressive optimization process in the universe, running in parallel at every energy level, in every living thing, for four billion years.
White Hat Guy: It's still just code.

Person 2: Ok, try opening google.com and clicking "view source".
White Hat Guy: Ok, I- ...oh my god.
Person 2: That's just a few years of optimization by Google devs. DNA is thousands of times longer and way, *way* worse.
White Hat Guy: Wow, biology is *impossible*.
{{Title text: Researchers just found the gene responsible for mistakenly thinking we've found the gene for specific things. It's the region between the start and the end of every chromosome, plus a few segments in our mitochondria.}}
