love this — we have to chip away at that inherent shamefulness that “not invented here” evokes. History is absolutely the best place to see these breadcrumbs and warning signs. We have to think of history as the penultimate open-source. We can choose to pull from that well, or charge out on our own — wholly unprepared.
This takes a bit of work on a personal level, to learn to set aside ego and recognize the potential for greater impact.
