Maybe someone more familiar with Vitalik Buterin can fill me in here...

Vitalik mentions that he's interested in both approval voting and quadratic voting. He seems to say that quadratic voting is exciting because it's "more optimal" in a certain sense, compared with score voting. But Will Jarvis highlights the tension between optimal vs easy-to-understand:

Jarvis: "And is there [...] a trade off [...] between a system that’s more optimal, but it’s harder to explain and kind of illegible to people to one that’s easy to explain, and somewhat easier to implement."

Is the implication that Buterin likes quadratic voting more in principle, but he supports approval voting because it's easier to explain and implement? I wish they'd spent more time on this section!
