I speed up almost every thing I watch or listen to 1.25 to 2X. It doesn’t work for all types of content but – most of the time – it is more efficient.
There is always the question of comprehension. My level is bound – to big extent – by my childhood, where I watched and listened to things at base speed.
Now my brain is less plastic. Changing my wiring to comprehend more of the faster speed will take years.
Since our language comprehension happens at childhood, would kids be able to comprehend more in less time if they always watch/listen to things at faster speeds? If yes, does this mean we are able to have humans that are capable of processing more information than us?
I don’t know.
