Fredkin’s original digital-universe theory has “very serious impediments towards a classical digital universe being able to comprehend quantum mechanical phenomena”. But swap the classical computational rules of Fredkin’s digital physics for quantum rules, and a lot of those problems melt away. You can capture intrinsic features of a quantum Universe such as entanglement between two quantum states separated in space in a way that a theory built on classical ideas can’t.

Does "towards" here mean "with respect to"? But even so I don't understand the exact meaning of "impediments" here. It seems to mean either "(Fredkin had serious) difficulties (in understanding a classical digital universe being able to comprehend quantum mechanical phenomena)" or (Fredkin's original model still had serious) flaws (if it wanted to be a classical digital universe being able to comprehend quantum mechanical phenomena). The latter appears to be more likely. I am not absolutely sure.
What does "impediments" mean there?
