And yet, who else in modern history has driven as many companies to such such success, and lead the creation of so many great products?
We had a ton of the NeXT machines at my university, and I still believe they, more than anything, demonstrate the height of Steve's capability of creating a company and product. Anybody who used Sun's Desktop OS and associated applications 5 years later saw how far ahead of the market NeXT was. I thought it was a far superior product to the Macintosh, which, by 1993/1994, was starting to get long in the tooth, and by 1996/1997 had fallen behind Windows in platform power/flexibility, causing me (never particularly religious about the platform I worked on - best tool for the job and all) to leave the Mac behind and switch to Windows (Followed by a switch back in 2003 when OS X took the lead again)
Does anyone honestly think Apple would exist today (and certainly not in it's current dominance) were it not for this single individual?
And, is it really a coincidence that Pixar rose to the heights it did with Steve at the helm?
Sadly (speaking as one) - technologists are for the most part fungible, you can swap out one for another. Designers/Architects are somewhat more rare, but they can be identified, recruited, and hired.
But Geniuses/Leaders - they come but once in a lifetime, and we admire them for that uniqueness.
Certainly doesn't mean we have to like them as people though.
