Something came to mind. If I understand correctly, even citta is quantized. So, can I safely assume that there is nothing in this world that is truly analog in nature? What appears to be analog is due to our brain being the bottleneck in information processing. Unless there is something out there that is at least the speed of a citta rising and passing away, we can never know for sure the existence of such analog nature. For instance, an audio signal. What appears to be a continuous audio sound wave is only as analog as our citta arising and passing away speed.
