Interesting insight, thank you! I think crowd-based approaches and machine-based approaches will always have very different strengths and weaknesses. The quality of algorithmic answers will generally (always?) be well below that of human-written ones, especially at first. However, in the long term I can see machine-based approaches "winning", simply because of their near-infinite scalability (and the sort of insight that emerges from enormous scale). Take web search: if started out with hand-curation in the portal era, until that got wiped out by algos and scrapers that could better manage the growing scale of the web (and exploit patterns only visible at scale, like PageRank). Human knowledge, including the sum of personal experiences of the people who express themselves on the web, is now at a size where it is no longer human-manageable. I see enormous potential here to extract, understand and navigate that knowledge using algorithms.
