Science isn't engineering. Science is about systematic knowledge, not 'elegant', aesthetic implementation to accomplish a purpose. You were claiming a while back there isn't any objective purpose, no values, no "good vs evil" to life.
Yet now you claim engineering, which is more or less "beautiful" according to how well it optimizes value-based parameters (including subjective-aesthetic values) is a science and not an art!
You are not consistent; you are self-contradicting!
The issue here is that many
Darwinian axiom? Survival of the fitest? The best compromize, optimization, between more and less conflicting values?
That isn't an art? Consciousness and neural networks are nonlinear. The solution-space for even simple problems blooms into complexity which overwhelms available finite resources to rigorously and thouroughly search to find a single, optimal solution.
Therefore, multi-paramater optimizations are an art, an educated guess based on expereince, experience based on appreciation of subconscious concept integrations of learned appreciations for pattern and simplicity.
Often genious is born, not learned from a math book. It is a subconscous expression of joy, not a learned skill.
