Their optoelectronics/optics tech is getting to the state of the art in a short period by their pace of progress from the rumors that I heard.
I'd wager 3-4 years before they have EUV themselves while avoiding conflict supply chain. Not 10 years time as you say.
They got some of the best minds on the planet working, so I wouldn't think that they cannot achieve it rather quick.
Zeiss and ASML are going to have real competition soon.
