Regarding your last paragraph, I see the Profile 1 vs Profile 2 axis as basically distinct from the Doer vs Thinker axis. People can spend years in large companies without ever needing or developing a get sh*t done mentality, and otoh starting an EA org and rapidly iterating can be a great way to develop or exercise that skill (see e.g. BlueDot Impact, AI-Plans.com). Maybe it’s that you’re leaving out a Profile 3 - people who start their career in (or very quickly switch into) EA but by starting a new thing rather than working their way up the ladder of an EA org. (Though the starting of a new thing could technically happen within an existing org as well).
