Earlier quoted context omitted.
Isn't that cart before the horse? The concept of investing is taking a risk. If you want to invest in only successful products after they're developed, there's no wealth delta to be a part of.
I would want to invest in projects that I think will take off. For example, if I had to invest in Tesla, I would not invest in the Cybertruck. In fact, that project turns me off investing in Tesla entirely. But say, the Model Y, on the other hand is something I think will be successful so I would bet on it
The same goes for Apple and Airpods.
