I think even with this technology that can put knowledge into our brains, normal people wouldn't dare use it. Why don't you use it? Let's break it down.
First of all, how our knowledge comes about is that we read a book or hear something, and then repeat it over and over again, transforming it into our memory. This knowledge is formed by the same principle as our other memories. If there is a chip that can give us direct access to knowledge, it is nothing more than writing a memory in our brain. When memories can be written down, can we, as ordinary people, still believe that the memory in our brain is real?
If this technology really exists, then someone must use it in other fields, and maybe we will be written into the memory of war, making us war machines. Perhaps we will be written into antisocial memories, making us an instrument of harm to society. In particular, there are a lot of racists, people like Hitler, who hated Jews, and if you have this kind of technology, then one race can be enslaved by another race, and that's terrible.
Writing knowledge can be achieved, so reading is naturally more simple. With this technology, our thoughts may no longer be our privacy, we will be completely exposed to some people. Because our memories can be read, and maybe even erased.
So, even if this technology comes out, it will be destroyed, because humans will not allow such technology to come out. Such things only exist in science fiction.
Do we still need to learn? Nature is needed. We need knowledge, but what we need is knowledge transformed by our own memory, not acquired through other means. There is no shortcut in this world, if we take the shortcut, then we will definitely lose something else.
