Exactly. "If a person can drive a Honda, how well can he drive a Mazda?". Duh, just as well as Honda.
And just like the natural languages, the more you know, the easier it gets.

If a pilot is only type-rated to fly an Airbus 320 he is not allowed to even try to fly an 737 nor a different type of Airbus. This attitude of "a car is a car, what can go wrong?" is deadly in some domains.

In my (corporate) role most of the people around me have over 20 years of experience in a very specific domain (manufacturing execution systems) and it takes about 5 years to train a new person. Having someone new productive in month is a dream for us, but it never happened.
If you can be productive in about a day, please explain why a pilot gets ATPL (airline transportation pilot license) after a minimum of 1500 hours of flight. Also please tell if you would board a plane where the pilot has 100 hours - that's an awful more than a day or even a week.
For skilled, experienced programmers, most mainstream languages become an implementation detail. You have to spend time learning idioms, footguns, and generally the way the language manages memory, but you absolutely can be great at 7 languages because they fundamentally do many of the same things.
I haven't hired people based on "their stack" in a long time, and it's been completely fine. Someone with skills can quickly learn your stack and be productive in it. I personally jumped on a project as a coder a few years ago having never written C# before, and I was productive in about a day. All the concepts were familiar, and the stuff I had to learn was mostly syntax.
