One day we'll get to the plateau of productivity of this hype cycle and wonder WTF were we thinking.
Not that we won't have most code written by agents. I truly beleive that to be true. But that we got so far down the "never look at code" rabbit hole that our abstractions will become so divorced from the reality that is the actual.. freaking... code. We will truly have spaghetti code, bloated towers of babble.
We'll tut-tut these times and think "if you only spent half a day thinking about the big picture, looking at code, dare I say write some code you could have saved the project a whole mess of trouble".
In the meantime we're going to be generate 10K in spaghetti what should probably be 500 reasonably understandable LoC.
Spending a day reading some code can save you $100s of tokens, and weeks of headaches.
