The major question is when do we become rich....
Depends on how you define it.
Smart folks have said they will hold TSLA for at least 5-10 years. I doubt riches will take that long. Elon's prediction of "feature-complete" FSD by year-end triggered widespread ridicule. But that ballpark now seems more likely because of yesterday's software update and Andrej Karpathy's recent speech.
As I've opined before, the arrival of FSD will be a Singularity in the transportation industry -- as unpredictable as the greater Singularity coming from general AI. But when the forward-looking Market sees the launch of Tesla Network and calculates the potential profits, I think we can predict the stock will head straight up. The only question is how high.
And that blastoff will come after all the other catalysts this year: Battery Day, more gigafactories, S&P inclusion, etc. etc.
So to answer your question, my guess is 1-2 years to become rich, 5-10 years to become super-rich.
