I've started to learn to play the piano over the last couple of weeks.. At the ripe old of 40 something... Do I wish I could just Matrix style upload the required skill into my brain? Sure.. But where is the fun in that.
Some things in life are worth taking time over, something lost on generation Z sadly
haha +1 rep for awesomeness.
Been playing the Piano & guitar since childhood and I'm not far off you in years
As proficient as I like to think I am (play in bands) etc, what I'd still give to download matrix style the prowess of some of my guitar heroes (Mark Knopfler / Gilmour etc), or the sheer piano extravagance of some of the all time greatest pianists like Sergei Rachmaninov.
I tend to look at music differently from someone who isn't musically oriented, and I regret that, I would love to sit down and listen to music for what it is, but I cannot. I'm dissecting every note, passage, phrase.. I listen to me play, listen to someone that IS a master at what they do, and momentarily dislike everything about myself... In frustration I wanna quit. Then go and sarcastically play something to enforce that really i'm an amateur in comparison, and someone comes in and says...... Ohhhh.......... M.................... G..... you're g awesome, where did you learn to play.
So I think no matter how well you can or cannot play, having a turbocharge of someone elses technique, or technical instrumental prowess downloaded into your head, you can incorporate and use to fill gaps in your own way to play. Some then argue that you lose your individuality if suddenly you were Steve Vai in your mind or, Bach or whoever... but in the grand scheme of things, I'd download it into my brain any day

(as long as it didn't blow my mind up)... but from all accounts i'm only using 10% of brain anyway with the rest as a silent humming in Dm

EDIT : But on topic I'd compare Engineers to trying to play a G on the 15th fret and someone has helpfully de-tuned every string, and snapped 2 of them off for you, including the
root: to make it 'more challenging' and to stop you going directly for the chord. Which doesn't help if you just want to play the chord! (nor any other note or chord on the guitar).
