He was one Of a handful of individuals who literally shaped our modern world. Whether he was a "nice guy" or not is not particularly important; I think he was a decent man and a tough competitor who's mark is stamped on our daily lives. He was a true American original and irreplaceable in any number of ways. He was the Edison of our age, with a singular sense of "cool".
What's interesting is that he's always been the darling of the Left, though he was one of the most masterful capitalists of his time. He was the epitome of what many of these people despise the most.
Somewhere, he may well be having the last laugh at his most ardent disciples.
