Elon has been wrong for the past 6 years on this topic: 2015 - 2020. He will continue to be wrong for rest of the decade.
I wonder if Elon actually believes what he says or just continues to play the con man?
Elon is a serial optimist. Most likely a super optimist. yes, I like how that rolls off the tongue... Super optimist.
Reminds me of Wile E. Coyote.
Most inventors and entrepreneurs are. They have to be, because who in their right mind would even start something that they want to do.
Elon may be worst than most... an EV company AND a space rocket company AND a tunneling company... Come on, man be realistic!
I have worked for people like him. Their favorite line is: "How hard can this be?"
They are great visionaries (like Steve Jobs was) and they do some incredible things.
Remember Steve's quote in 2007 saying "this will revolutionize our world" when introducing the Iphone...
He saw the future (I did not until much, much later). Some people just see things differently than others.
Jacques Cousteau was an aviator but a auto crash while going to attend a friend's wedding derailed those plans.
Eventually he re-focused his energies to underwater instead of above water and helped to invent the Aqua-Lung and do many, many cool things.
It is this diversity that brings about new ideas and products and makes this an interesting time.
This should be celebrated. Remember, if man was meant to fly, he would have had wings!
I think its a mix of both. The lack of transparency is the problem. For example, the rewrite. He mentioned that a year and a half ago that that had been working on it, but never mentioned it before, so they clearly knew the initial method wouldn't work.
Much like how Space X works, they try something and fix the issues. With FSD, I have heard we'll have self driving cars since the early 1980's. Most people don't realize how complex driving is because it is now simple for them. Humans are great at filtering out unneeded information. Computers are not. They have to be trained what to filter and what not to filter. When you are teaching your kids how to drive, hopefully you mention that in a neighborhood environment, a bouncing ball is extremely dangerous situation. That is because likely there is a kid or dog chasing that ball. Every sign (yard sale, speed limit, Yield, etc...) needs to get processed and filtered as needing more attention or not.
So I disagree that the "clearly knew the initial method would not work". They discovered the issues and are now working on a better solution. You need both a good ideas and also a lot of hard work and a unhealthy dose of optimism to succeed.
How many times did Wernher von Braun's rockets fail before he helped to design an build the Saturn 5?
