> Leonardo da Vinci was human, he had flaws, he wasn't always right, and I think these are important things to point out in order to make the real achievements stand out.
I don’t think any, or many, people believe da Vinci had no flaws. He was, however, indisputably brilliant in many ways, and is the literal embodiment of the Renaissance Man / Polymath.
It takes a specific type of person to be confronted with a persons’ achievements and say “well, you know, they still had their flaws, and not all of their ideas worked.” Da Vinci was a known self-critic, nobody was harder on him than he was on himself: he lamented on his deathbed that he had offended god for not being better at his art.
I’m unsure what you are contributing to the discussion.
