Early tech investments are risky, but if your competition has tech 10 years more advanced than yours, there is probably no amount of money that would allow you to catch up, surpass, and make enough profits to recover the investment, mainly because you can't buy time, and your competitor won't stop to innovate, they are making a profit and you aren't, etc.

So to me the main realization here is that in tech, if one competitor ends up with tech that's 10 years more advanced than the competition, it is basically a divergence-type of phenomenon. It isn't worth it for the competition to even invest in trying to catch up, and you end up with a monopoly.
