This is highly speculative topic, but Tesla is all about future. 500k cars/year thanks to Gigafactory it's just the start. There can be delays (or can happen little sooner), but let's assume, that it's quite sure it will happen. I mean Gigafactory, Model E and 500k+ cars/year. The big plan is to change whole industry. So how much Gigafactories have to be created and how? How much - let's have very conservative assumption that yearly world production will be 100M cars. That means for big plan completion there is need for 200 Gigafactories. One can be optimistic and have faith in efficient recycling, but energy storage is not only about cars. And that's not big difference for this speculation: will there be 150 or 250 gigafactories. What's your opinion - who will own it, in what possible time-frame they can happen, who will build them, what share in this will have Tesla? When and how others will join this race for this new market? How this will influence the world around us? I mean in terms of jobs, mining, new economic giants etc. IMO Tesla is currently building bridgehead of a whole new... era. How this era will look like and how will it happen? I, personally, am totaly convinced that it will happen. The only questions for me are: when and how and what will it change? Just like SolarCity CEO said they want to be the biggest utility company in US basing only on solar power. The future shine on today. Thanks to people like Musk & Co. we can look into it. What do you see there?
