it's still around just a lot smaller than before. when everyone was encouraged to take near free college courses while the media promoted amazing technical advances you get a shitload of engineers that want to work on cool shit. now every engineer i know is the son of an engineer and no one else is really getting into the field. you still have the mic producing insane feats of engineering but if you recruit from there for a moon shot you at least temporarily slow weapons development.   like any young industry it has moved from being mainly extremly smart researchers and skilled craftsmen to being a mass produced product you can easily buy the tools to make. it's both good and bad because i'm glad the cost of someone hand shaping the panels of my car is no longer required but if i need a one off sheet metal product there is no longer a pool of thousands i can ask to do it.
