That is an interesting question. Here you can see the actual popularity of each library within Boost: https://grafikrobot.github.io/boost_lib_stats/. Also, see the comments at https://www.reddit.com/r/cpp/comments/130bzj8/has_boost_lost.... My company has been heavily utilizing Boost.Asio and Boost.Beast, so we've definitely reached for Boost in newer projects as well.
