Funny, "organic software" is a mental label I have for how most human written software is produced/functions: software that could not be rebuilt from scratch, because it's construction was highly path dependent and dependent on implicit know-how distributed across irreplaceable individuals; an accumulation of unprincipled designs and patches.
That only (sort of) works on the VERY top level - with user-facing apps.
No one is going to want "organic software" for their Node runtime, their web browser, or their OS. Some things just need to work, and work efficiently, 99.999999% of the time.
For some uses cases I think this might even work out well enough if you figure out and apply the right guardrails and boundaries. That's quite a big if though...
