> because I have decades of experience with analogous or ancestor technologies (like C and C++, SQL, Unix) I think a lot of people underestimate just how much knowledge transfers between systems within the same domain. I have nowhere near your length of experience, but even in just my time I've been able to pick up plenty of languages and frameworks and get going right away because I already learned the underlying concepts when working with other similar systems. No one should be starting from scratch every single time they start something new, and the larger your variety of experience the faster it's going to get each time you start with a new language/framework/system in that domain.
