They both blazed a trail, Steve Jobs was better at taking existing ideas and redesigning/repackaging them and bringing them to market as premium/experiential products. Elon Musk is a real innovator and who is able to envision bring to reality a vision that pushes the envelopes of what’s possible.
I’d say that it’s likelier that we’d get closer to where we are now with PCs/handhelds without Steve Jobs, than we would with a whole host of things without Elon Musk.
