It's very easy to say this on HN.
I'd like to see you say that with a straight face to a war widow or a mother who just lost her child though.

A simpler scenario; I meet you and decide, for whatever reason, to kick you in the dick. In this moment, you are no longer an absurdist: your whole world is pain; pain is literally the only thing you can perceive. Now, post dick-kicking, when you eventually convince yourself again that nothing really matters, does your perception of me change? If so, why? If not, why? And why do you value your pain over the war widow's?
But yes, we can only follow our programming. Part of that programming is creating narratives and assigning value judgements to elements of those narratives and our sensory experience. Your narrative overvalues your understanding of basic structures you have a naive understanding of, while suppressing creation of those of a social level. If you find life absurd, its because your outlook leads to internal schisms.
You asked why we dance, and then referenced Ex Machina. Kyoko has no free will and is programmed to dance on command, and yet dancing seems like the one thing she actually enjoys. Is there meaning in her dancing?
And what if it isn't?
And if you choose to cause suffering for others in the belief that somehow it doesn't matter, then aren't you just shoving your beliefs down other people's throats?
your shitty attitude stems from the same function.
edit: Maybe a better question is, what is the objective measure of silliness?
If I understood you correctly, your answer to "what is the objective measure of silliness" is essentially to say our best model of nature is of particles in spacetime adhering to certain rules. My, and what I assume is the common definition of silly, is inconsequential incoherence. Perhaps your definition is different? Nature is not silly, since the consequences of its rules are both measurable and consistent. If you're saying its absurd to think of human society in terms of physics, well sure. Don't do that, its the wrong layer of abstraction.
