Agreed. Time and time again, I wished I'd knew Ruby and/or RoR. Do you know any good (and "boring" as in time-tested & practical) tutorials/learning resources?
"Programming Ruby" [0] ("the pickaxe book") and "Agile Web Development with Rails" [1], both from Pragmatic Programmers.
I learned Ruby and Rails through them in the late 2000's; they are still being released as new editions. It has been a while since I bought new books from PragProg, but they used to have a recurring sale of ~40% off around late autumn (thanksgiving?).
Ruby/Rails and its ecosystem continues to prove itself the practical, boring, reliable workhorse option.
