This article is a stub. It needs to be expanded.

Just some notes for now …

Ready-fire-aim philosopy

Discoveries and scientific progress by

  • working on practical problems (where ideas come from (?))
  • failing but discovering something different
  • which can be applied elsewhere eventually

Related is (highly speculative): The source of new axiomatic wisdom

Focus on growth plan (cellular automata)

Yes, I agree that the von Neumann bottleneck from
separating storage and compute (arithmetic logic unit ALU) is very bad.

But personally I think maximally distributed compute (cellular automata) is only useful in special application cases. E.g. far term utility fog.

I don't like the imperative nature of "what to do" step by step in a "growth plan".
I prefer the denotative nature in a direct description.
See: Decompression chain & Constructive solid geometry

Well, a "growth plan" could be an automated step within a decompression chain.
Actually extrusion in a nanofactory chip is kind of a growth plan.
Just that the assembling nano and micro-machinery does not push itself along but rather stays put and pushes the product.

There is a bio-analogy to the (topologically 2D) "meristem" "germinal epithelia" "germinal zones" "germinal cells".
See: Complex surface nonplanar nanofactory chip growthfronts
Also see: Misleading biological analogies that should be avoided

Reminder: Full volume growth would lead to
