This is a subjective assessment. I just assess the level of general knowledge that was in my childhood with my peers. And in modern schoolchildren. Of course, today a lot of new knowledge has appeared, which was not in our childhood, but in general, it seems to me that education has become worse. Children less understand how the world works, less feel causal relationships in it. More use rough memorization and instructions, rather than understanding and creativity. A very common reaction, such as "This Lego set allows you to collect only one design". Damn, in my childhood, we almost never looked in the instructions for designers, they all came up with it ourselves Of course, this is all very fuzzy perception, and in my childhood there were a lot of stupid schoolchildren, and today there are talented. But according to the average estimation it seems to me that modern children are less aware of the world around them.
