Efficiency comes from agency, vision and creativity, not typing speed. All three of these can be and are boosted by having a full time career coach on the phone in your pocket.
I mean using it as a career coach is a different direction and one that I think is a moderately good use. Passing on rote knowledge is basically what this thing is for. Except... I'm not sure anybody really knows what good career advice is right now. The best you could do is to go find a bunch of people who disagree and then decide which arguments convince you and why. A leg up, ok, but I don't see shortcuts to that process as increasing creativity, agency, or vision.
Ah yes three things you get from a training corpus consisting of blogs and stack overflow posts. I’m frankly surprised it doesn’t say closing this question as off topic halfway through a chat.
