Previously I made this set of statements:
Computation irreducibility, the principal (unproven), suggests the best we are going to be able to do to understand EVERYTHING is just to keep computing and observing. Everything is unfolding in front of us and it’s “ahead” of us in ways that aren’t compressible. This suggests, to me, that our best source of figuring things out is to CREATE. Let things evolve and because we created them we understand exactly what went into them and after we’re dead we will have machines we made that can also understand what went into them.
This is a rather bulky ambiguous idea without putting some details behind it. What I am suggesting is that the endless zoological approach to observing and categorizing “the natural world” isn’t going to reveal path forward on many of the lingering big questions. For instance, there’s only so far back into the Big Bang we can look. A less costly effort is what is happening at LHC, where fundamental interactions are being “created” experimentally. Or in the case of the origin of life, there’s only so much mining the clues of earth and exoplanets we can do. A likely more fruitful in our lifetime approach will be to create life – in a lab, with computers and by shipping genetic and biomass out into space. And so on.
This logic carries on in the pure abstraction layers too. Computational complexity studies is about creating ever new complex systems to then go observe the properties and behaviors. Mathematics has always been this way… we extend mathematics by “creating” all sorts of new structures, first we did this geometrically, then logically/axiomatically, and now computationally. (I could probably argue successfully that these are equivalent)
All that said, we cannot abandon observation of the world around us. We lack the universal scale to create all that is around us. And we are very far from exhausting all the knowledge that can come from observation of what exists right now. The approaches of observation and creation go hand in hand, and for the most important questions it’s required to do both to be anywhere close to certain we’re on the right path to what might actually be going on. The reality is, our ability to know is quite limited. We will always lack some level of detail. Constant revision of the observational record and the attempt to recreate or create new things we see often reveals little, but critical details we miss in our initial assessments.
Examples that come to mind are Bertrand Russell’s and Whitehead’s attempt to fully articulate all of mathematics in Principia Mathematics. Godel undid that one rather handedly with his incompleteness theorem. More dramatic examples from history include the destruction of the idea of a earth centered universe, the spacetime curvature revelations of Einstein and Minkoski, and, of course, evolutionary genetics unraveling of a whole host of long standing theories.
In all those examples there’s a dance between observation and creation. Of course it’s way too clean to maintain there’s a clear distinction between observing the natural world and creating something new. Really these are not different activities. It’s just a matter of perspective on how where we’re honing our questions. The overall logical perspective I hold is that everything is a search through the space of possibilities. “Creation” is really just a repackaging of patterns. I tend to maintain it as a different observational approach rather than lump it in because something happens to people when they think they are creating – they are more open to different possibilities. When we think we are purely observing we are more inclined to associate what we observe with previously observed phenomenon. When we “create” we’ve already primed ourselves to look for “new.”
It is a combination of the likely reality of computational irreducibility and the psychological effect of “creating” and seeing things in a new light that I so strongly suggest “creating” more if we want to ask better questions, debunk false answers and increase our knowledge.
