I generally agree as somebody still fairly new to development. I'm about 6 years into focusing in computer science, and early into the process I heard about vim and emacs. I knew that it wouldn't be necessary to use either while going through undergrad, but I decided to learn enough vim to be functional just because I wanted to understand. Vim still isn't my exclusive dev editor, but it has almost become my exclusive terminal editor. Learning older technologies may not always be top priority, but it can do a large amount to enrich your personal perspective- particularly if you discover the niche where its usefulness is best utilized (and like you mentioned, if the amount of time to get up to speed will save you proportionate future time).
