This all has been said already months ago!
Typical modern age nonsense meeting to promote a brand...
As Tesla owns no stake (patents) in battery technology I expect that Tesla, within three years will be surpassed by at least 4 other car manufacturers and best case will rank world number 5 in selling electric cars.
All Musk does is making as much money with with vapor ware (= paper only ideas) as is possible. The reality will get him soon and Tesla will remain a niche player for fancy sports cars.
I definitely see it differently. Here is an article below about what Tesla is trying to put together. Basically everything they do is focused on bring the cost of battery technology and manufacturing down. Yes, they make fancy sports cars, but their larger goal is to make a battery powered car that will sell for $25,000 in 3 years. To me that is ambitious and would be a great engineering achievement.
I agree with you on the competition, and that Tesla still needs 3 years to pull this off. That means Volkswagen and Toyota will have three years to achieve the same thing.
But Tesla has put a lot of money into its supercharging networks. They have a lead there, and that will come into play.
While the larger tabless batteries that they unveiled yesterday are just a single engineering step forward, it's steps like these that get us slowly into the future.
Musk made his bet on electric cars, solar, and batteries for grid level storage. Those are good bets right now. You could say he was right. They are the ones that are coming to fruition.
I want an energy breakthrough like everyone else here, but until someone can commercially produce that breaktrhough, batteries and solar are some of the the best solutions we have.
