I am more recent in applied math (coming from pure) but my impressions are very similar. For the last few years I keep discovering the same thing over and over again: the level of math in “technology” is abysmal, nobody understands it, nobody needs it. Incidentally, I am writing a blog post about PageRank right now. Short version: mathematically, it’s very unsatisfying.
