I'm not sure what the author's intention was but to me this comes across as 'damning with faint praise'.
I wished we had some real role models in tech. Who would you propose?
I find Plane Crazy really charming, although it's a portrait of someone who I definitely wouldn't do business with.
I also find it endearing that the OP thinks that he'd have been just as good as the modal successful startup CEO if one of his ideas had accidentally hit (despite him.) I agree. There are a lot of Cringelys running massive companies, but without the heart that he had. The man seemed an often self-destructive dreamer, but not evil in any way as far as I can tell. He seems to have honestly liked people, and to be driven by wanting to impress them through making their lives better.
