OTOH you have Intel which never stopped R&D and they still have lots of trouble catching up; arguably they've been trying for almost a decade now, five years if you're being generous. (And they buy tools from ASML! Which other posters explain will also be the case here.)
IMHO Intel's case is more nuanced, they were milking their position until Apple did something extraordinary with TSMC. They are also a giant corporation who has to re-organise and restructure, therefore can't move as fast as a newcomer. Intel's case is a business case, more than an engineering case. Just as Nokia.
The point still stands: they have the infrastructure, the experience, the logistics and the supply chain all secured and they're still at least a couple years behind if not more. It's extremely optimistic to say that it's going to be easier to start from scratch.
Intel was receiving continuous beatings from AMD (Ryzen/Epyc) a few years before Apple came up with M1. 2016/2017 vs 2020. I don't think Apple and Intel are in much competition: Intel doesn't make laptops and lacked Apple's moat when they did, and Apple doesn't sell (amd64) server CPUs.

I mean, that's true from a business perspective.
But they were trying very hard to make the next process node work. They went from a process upgrade every other design generation (the famous "tick-tock") to just tock-ing at 10nm because they couldn't get the next process generation working.
