And to be clear—I mean to ideate and create new ideas channeling that optimism to spur creativity, enabling you to imagine that future and refining the ideas publicly. (Good reminder to me not to post before I finished making my thought make sense. 🤦‍♂️)

Define 'proof of work.' If imagining something and refining it in public is POW, every open source project qualifies. The difference is whether the work is rewarded by the network.

By imagining it and refining it in public. That's the shortest description of Bitcoin's development philosophy. No permission. No gatekeeping. An idea, iterated in the open, proven by work.
