I think this entire comment thread is using the wrong definition of the word "quantized". There are two relevant meanings of this word 1. Something split up into discrete chunks (like integers vs real numbers) 2. Something which acts quantum mechanically (i.e. with superposition and entanglement and all that stuff) In this context "space-time is also quantized" means space-time is acting like a quantum system. Whether space-time is discrete or continuous is a wholly seperate question. There is no particular evidence that it is discrete, but if you make the discretization scale small enough it theoretically could be. Most things work more nicely if it is continuous though.
