He may still be around but he will be remembered as the guy who missed the "big one."
Would you like to be remembered as the guy who said Microsoft, Apple or Google is only worth a $1 per share?
My first boss was a great engineer. The first day I showed up to work I had a very expensive hand-held calculator. My graduating class were not allowed to use them on tests because they were so expensive and they felt the $300-$400 HP calculators gave an excessive advantage to "rich" students (They did not consider some students worked and bought them with their own money).
Anyway, when I showed up for work my boss was using a slide rule. He looked at my fancy calculator (which by the way you can buy the equivalent for $30 today) and said it was just a toy and would never replace the sliderule. As brilliant and talented as he was as an engineer I still remember how incredibly dumb that statement was. It took him two years but he finally retired his sliderule.
I will always remember Feuerstein as the guy who missed the "big one."
