Agreed each race has different views of the world that allows the to manipulate it in various ways. Fallen hack vex tech better than any others aside from Clovis and Asher. Hive crack literal planets via "magic". Awoken copy the hive and spin their own twist and mess with wish dragons. Humans had some developed tech but are not known to have left the solar system, with the presently notable achievements being things like blackhole guns, exos, and neomuna's cloudark. Cabal have made star destroyers, psychic power experiments, jetpacks, and gene editing therapies. Really hard to say any have lower intelligence except for awoken who copy the hive in some of what they do.
