> This happened literally all the time. 1. That ↑, but also… 2. … the spread of lightbulbs or automobiles happened organically, simply because people perceived them as better than what was there beforehand and wanted them. There was no big centralised push like "We must switch from horse carts to 100 % automobiles within two years in order to avoid the big horse dung apocalypse", so the spread of those new technologies simply happened at whatever speed was feasible and sensible. If it turned out that building the required new infrastructure for lightbulbs or automobiles was a little harder than initially estimated, the buildout simply happened a little slower and that's that. Whereas now there are external goals attached to the process (must have X % electric cars by 20xx in order to avoid the apocalypse), so if it turns out that reaching that goal is harder then expected, there's immediately much hand-wringing.
