Maybe the only comprehensible worlds are measurable ones, and timers emerge from measurement-constructed histories, so elementary tasks (those caused by timers) are possible if any "why" questions have answers. Why are explanations "possible"? Maybe bc only explainers survive.

I don't yet understand the Deutsch speak! How do you define task and constructor in normal computationalism?

I don’t buy the initial statement “Why is there only something...”. Due to quantum information theory there is everyting at the same time. So the question is, why can we see only something...”. Or even better: “Who the fuck is the audience?”

Perhaps I can express if for you as: Why is there something that conforms to quantum information theory at all?

Current physics has an appealing answer: Symmetry

The symmetry is the result, isn’t it?

Probably there is everything, we just can only see the bits near us

Most things are too improbable or too self contradictory to exist.

I doubt that anything can be infinite. But some things can be boundless. We should expect our universe to look infinite though, because if we'd live close to the boundary that region is probably not anisotropic enough to host us.
