Actually, Steve Jobs' track record is closer to 50-50 in terms of successes vs failures. The difference is that his failures were usually not very significant, and his successes were monstrous.
Are you counting the totally unprofitable development of NeXTStep as a success or failure (considering that NeXT would very likely have died had Apple not bought them)?
(Those same APIs and objective paradigms became the basis for the entire iOS app ecosystem, via MacOS...)
