It's The Beatles ^^. But yeah, Paul knows nothing about writing or reading music, really.
And I know very little as well. I mean, I know stuff like Cm7 and Ab13 and stuff but I'm not a genius when it comes to chords.
But I would most certainly encourage the use of knowing chords and being able to write them. If you don't plan on doing it for a living, I don't think it's all that important. But if you were to be a songwriter for other people or a studio musician, it would be best you knew this stuff.
But I highly doubt you are going to be a studio musician. But hey, I could be wrong.
