Books don't have a learning model at their core, their main aim isn't to impart information, but rather, to store it (this https://andymatuschak.org/books/ makes the point better than I did).
How does your new approach compare with the "fear heuristic" method you used previously?
Putting the process of reading a textbook into words, and a practical framework, helped me, but I think this post did not offer as much value as the Jenga tower one you wrote previously, perhaps due the "obviousness" of this post's material (I do recognize that although this may not be helpful to me, it is helpful to others).
Is there a way to build broad knowledge for sight reading pieces, or is it merely a matter of sufficiently immersing oneself by just practicing?
Yes, I am quite hesitant to leap into the Sequences, not knowing how valid the studies cited are. I too would like to know how some of the mainstay LW concepts fare in light of the replication crisis (as psychology especially has faced a lot of problems in that regard).
I believe you meant "in contrast with vertical search like Google".
I agree in general with your point about incentives. However, there is also another angle to consider: other companies. Google will have to keep innovating to some extent; if it doesn't, other rival search services may do so threatening Google's market share (although this threat would probably not be very impactful given the number of people used to Google).
