They mentioned the timeframe as 2006-2016. I think they were purposely omitting the recent gains to highlight their point about the unexpectedness of NVDA's stock jump.
So sure, if you correctly guessed that ChatGPT was going to spur a ton of interest in Nvidia hardware, then you could have made lots of money in not very much time. Meanwhile, to me at the time, this seemed like an incremental release on top of OpenAI's prior GPT models, none of which were earth-shattering paradigm shifts. I certainly did not anticipate the surge of all these AI startups that wanted to build on top of it, or the industry shift to try to use GenAI to solve all of the world's problems.

If I got the math wrong anywhere, it was the magnitude of investing that $1k in BTC back in 2011 -- I'd have $30-35 million to my name, minus taxes for long term capital gains. Even then, it wouldn't have been clear to me at what point I should sell -- mid 2017, when that investment would have grown to $1 million? After it peaked in December 2017 at $20k, it lost 80% of its value -- what reason would I have to expect that it'd grow to more than 3x its previous peak, just a couple years later?
