I love how Wolfram's personality shows through in every sentence. Not an ounce of humility. Maybe a bit off-putting on an emotional level, but it really communicates how strongly he believes in his ideas.
Our love for "humility" is really our rampant avaricious envy, greedy for everything every successful person has and petulant that anyone should have anything we can't have.
You can read between the lines and see the work being done on Wolfram Alpha during that time period.
Very interesting article to read. Plus I'm a UIUC grad and I remember driving by those offices so many times. Who would have thought they were up to such grand goal.
