I feel this depends on whether you believe concentration is a problem. Like before the Neolithic Revolution people didn't really have leaders, if someone tried to be a tyrant it was a lot easier to leave.
Though after agriculture and the ability to concentrate wealth blockchain is imo the first real shot of a store of value independent of a system.... though by creating a new system in which a few centralized players are in charge, humanity prevails
When you say "lead prospecting," what did that actually look like in practice for you when you were starting from zero? Like for me so far I feel I think too much of how to optimize whatever it is I'm building (which is the relative easy)
I'd guess it's popularized by Palantir which did the FDE model on a large scale (to great success) though it seems now the competitive landscape for AI implementation is broadening (such as openai implementation partners for ex)
