Is space-time fundamental?

Most scientists assume time & physical objects are fundamental. And that certain physical objects like brains poses a level of complexity that allows them to get conscious. 

Hoffman beliefs that it's the other way around. That consciousness creates physical systems. And that space-time is dead:

• proved by natural selection: because complex systems hide complexity -> space time is just an abstraction 
• the traditional physics has no operational meaning below the “Planck scale,” roughly 10 at the power of -20 times the size of a proton.
