That Musk is working on more fundamental problems is more than clear for anyone who has some core understanding of engineering and the underlying challenges when dealing with physical reality vs software based ones.
Jobs was a consumer oriented/marketing/product visionary person, in contrast, Musk is looking in the future and is trying to put GROWTH in the direction of solving some of the underlying fundamental civilization problems, and this is highly admirable.
Regrettably, as of lately, it seems that "Tesla" company ( and this implies Musk vision) is moving towards making their cars as difficult to modify as possible and in such is trying to undermined the growth of the only market that can compete with the NEW electric car vehicles one and that is the internal combustion engine (ICE) -to-electric conversion market. In the world there are over 700 million ICE card and everyone of them can be converted to electric, this is a huge market for the electro/mechanical shops, that will eat a big byte of the market for new electric cars. For that ICE-to-electric to grow it needs commodity parts that are easily swappable/interface-able between different brand components, this is what the electric vehicles car maker are realizing and are trying to undermine and curtail.
Of course, Musk is working through the corporate structure of the business and not as an independent entrepreneur/visionary ( as he would like to be perceived), and such he has to make sure that the shareholders get their part, and this, regrettably, leads to undermining any market competition even, if in the light of it, the world, in no doubt, will be moving in the same direction (and even A LOT FASTER) as in Musk's vision, and will be a better place even without THE HIGH COST inherently present in the selling of NEW electric vehicles.
