We do. Problem is, while individually, we're much smarter than bacteria, as a large group, we're just as dumb as groups of them.
Take our main coordination mechanism - the market. For all that's been said and written about it, it's still basically gradient descent. As greedy as it gets - in the technical sense. It's what's been driving the development of humanity ever since we formed societies. It's what controls the behavior of everyone.
We may think we're smart and have principles - and we do. But the reality still is, everyone is spending most of their lives trying to align themselves to exploit the local economic gradient - because that's how individuals get more of what they want, and less of what they don't want. Nobody is strong enough to single-handedly reshape the larger economic gradient. So while individually, we play complex games, at macro scale, we're not all that different from slime molds or fungal growths.
Maybe one day our economy grows so sophisticated it'll gain sentience. But that doesn't necessarily mean things will get better - much like an individual human being sentient doesn't mean their cells are happy.
