Is a constraint we imposed on it, when Conway invented life he was only considering unidirectional time systems.
the light-speed limit
Is a consequence of locality, which was also something we imposed because of convenience rather than something we discovered
the observer effect
Does not exist in life, I’ve seen a rather complex configuration that allows gliders to pass and detects them but does not interfere with their path in any way.

It’s a consequence of the fact that you just cannot compute Life backward, because it is indeterminate.

Not sure I understand you… is it possible not to impose that in a cellular automaton?

You may well be right, on reflection it seems theoretically possible.
You use “we” in your post in a way that implies you co-developed Life—is that correct?
I think you could allow non-local influences if you wanted, although if you define cellular automaton in a certain way it would no longer count as one.
As for the first, I think that assuming you take MWI rather than Collapse theories our universe can be computed backwards at the bottom level (if you take Collapse then you run into other problems, since life is both deterministic and local whereas collapse isn’t).
For the record, I did not co-develop life (it pre-dates my birth by several decades), and I did not intend to imply that I had.
