Trolman, this is Starcraft not Warhammer... our civilization took about 5000 years to advance to current level, warcraft tech level (not cultural or any other) is about 16-18th century, So that's about 500-300 years to advance to our level, plus 100-200 more to advance to space age shall we say at least according to Starcraft lore.
warcraft advances three times faster, so that will be 133-233 years, we have magic and already had contacts with civilizations that can have time travel, which boosts or advance to space in five times, so that should be 26-46 years, so if you say it took 35 years from HFT, we already should have nuclear energy, AK47s and McDonald's.
