projects spacex should be working on but probably isnt.
>zpe (alternative thrust tech)
>quantum computing
imagine a future where the full potential of quantum computing is realized. a giga server farm of quantum chips could out compute every computer ever made combined by a billion times. give it grok sentient.0. ask it to create a new form of energy propulsion that isnt combustion based like now. 2 weeks later you have a fully engineered blueprint for a zpe propulsion prototype. all you have to do is build and develop it. rockets become obsolete tech in 10 years.
