> The better the tool the less you learn from it This seems too broad to make a general rule. Shall I not use calculators and memorize trig tables to better understand the tools that are these functions? I would be interested in seeing that experiment, I cant come up with a concrete example in my head which would follow that pattern. > maps I agree, I think most people should not have to become experts on local roads, then again, I think you over simplify the issue. I would bet that most people are experts on their local roads. I am in my hometown, I am not when I travel. I do not know how pdfs are made today, but keynote/power point are generally drawn with WYSIWYG tools rather than post script or latex. I am not aware that I have ever read a pdf or been to a presentation with slides not generated by one of these WYSIWYG tools in my entire life. I have never actually opened one of these files, but I also don't expect that I could. I would bet they are not stored in text files. Overall I contest each of your points, though I appreciate the ideas. I understand the sentiment but don't agree on the reality. Sorry for the late reply, I'm happy to continue if you have the time.
