I wish we could capture the "inventiveness" of a particular project — how well the problem was understood when the project initiated.

There had been _many_ *nix'es by 2006, so the territory had significant prior art and with it collective deep understanding of the problems being solved. Angular sprouted alongside a number of other SPA frameworks in an ecosystem that was experiencing a "growth-spurt" (using that term loosely) — lots of variables.
