The point OP misses and apparently everyone here does too, is that if your goal is to become a better writer, you should absolutely read, but read with conviction to learn what makes a good or a bad book. You are not reading it for pleasure at that point. An Uber driver who drives a bus every day of his life is not necessarily better than someone who (a) is more skilled naturally and (b) deliberately practices for much shorter times to become a better driver. How is it any different here?

Cal Newport touches this in his books. The best solo violinists dont practice any longer or harder than the other violinists, they practice deliberately and that looks very different.

So in summary I think OP is pretty wrong. Asking people to just read more without adding this nuance is just going to create a bunch of zombies who read a novel a week and are none the better for it.

The only books that are required reading if youre planning to write are "on writing" by King and Strunk n White. Just memorize the latter. Then read your competition, carefully. Then just start writing.
