Big gambles have big risks. It's the gambler's folly, after a big win (ASML's EUV) to say, gee, we should have bought more lottery tickets! Next time, it all goes on red!

What is no longer mentioned is that ASML made another big gamble at the time they started on EUV. They decided to make an all-in-one chip making machine that took silicon and output chips (instead of matrices of chip circuits laid out on a wafer).

On paper, the machine would save a lot of money for the fab houses. IRL: no one asked for it, and no one was willing to risk their entire production on a single, untried, swiss army knife of a fabricator.

The whole program was a wash. People were reassigned and the project died a very quick death. ASML lost a ton of money on this misguided attempt, but not enough to choke them.

So, they rolled the dice twice, and one gamble paid off handsomely. If it went the other way, they'd be a smaller company, and Moore's Law would be overshooting reality. If neither paid off, they'd be DOA.
