Elon states that manufacturing is critically important to Tesla, and he implies, to many other industries. The theory being that if you can make the same widget cheaper and better than your competition through advanced manufacturing, you win. Obviously, Tesla has other strategies in place too, like design innovations.
The reason I bring this up is Apple. They seem content just managing their manufacturing partners, relying on their brand, ecosystem, design innovations, etc. Which is a kinda Warren Buffet way of viewing the world. Their iPhone ecosystem is very powerful and quite the moat. But not doing any manufacturing themselves seems to me like a long term problem for Apple, which is one reason why I haven't recently invested in them. Thoughts?
BTW, while I like GP for the medium term, they will have to improve their strategy for me to continuing liking them long term. They do own their manufacturing plants and manufacture their vehicles in house (plus), but they don't own much advanced technology that goes into them. For their industry, I don't think it matters for the next year or more, but it bears watching.
