Despite his mad and destructive social and political side, as an engineer and business man he is extremely smart and effective.
He makes lots of unnecessary major and cringy mistakes in both engineering and business too, but his net on both counts is astounding.
And while he may overuse it for PR, he has put himself at great financial risk when pushing through major capability developments and business hurdles. His rewards were earned.
But the sick picture of the richest person in the world, spamming stupidity, and harming countless numbers of people's lives in order to prop up his juvenile ego is hard to look past for many. For good reason.
He is a strong mix of both extremes of capability/impact spectrum, not just one.
