let's agree to disagree:
I agree, Napoleon was creating the basement of a new aristocracy, with inherited titles. He also accepted the titles of old aristocracy, and even tried to have them on his side.
I disagree, mechanism of napoleonic nobility was quite different from the old one.
No ridiculous pretent of being of another blood than the commoner, or God chosen.
No prevention against traders, industrials, scientists, artists
No privilege towards taxes, laws, career. Heirs who chose the army had to learn the hard way, in battle.
So to check whether heirs were talented or not is irrelevant: they inherited titles, not privileges, contrary to Old Regime.
