Mayhap. However, each individual has a differing capability here. And as well, each has a differing capability, with different aspects of their brain. For example, the path for "reading" is something like "vision -> deciphering squiggly lines/patterns -> words -> comprehension -> interpretation -> contextualization -> on and on." And as you mention, there are many other processes in parallel, such as focus/attention, etc. You could get tired at any of these points, yet the neuralink may bypass many of these steps! So one may literally be able to absorb greater info, without fatigue. Of course, this is a far greater cause for concern than some realise, for example... Right now, each of the above steps (and more, I'm just spewing a few examples as a 'path'), have built in, evolutionary derived 'filtering'. Your visual cortex, for example, filters and processes info. Deciphering 'random marks on paper' into patterns, and then words, with meaning? More filtering and processing. All of our senses are filtered, processed, managed by portions of the brain, prior to being interpreted by our multi-layered, multi-faceted mind. What I fear is that a neuralink like device may bypass much of that filtering. That processes to allow critical thought are even more complex than we think, and may reside in specific areas of the brain. I know that I walk away with differing levels of comprehension from something read, spoken, or watched. I suspect that 'interpreting information' is highly source dependent, and that we learn to interpret, to 'tune' the same sight/sound/vision as the same event. I guess my point here is simple ; bypass parts of the mind when inputting data, and the outcome is uncertain. Imagine reading news articles, or watching a video, with some of your interpretive / critical thinking bypassed? (I'm sure someone will point out "No, part $x of the brain does that job!". Sorry, I say NO, that's my whole point. Our brains are not a machine, with a CPU/GPU/NIC or what not. Just look at the insane complexity of the visual cortex.)
