What does Donald Trump teach us about the nature of existence, and epistemology, in general?

Many people love Donald Trump, and many people hate him. However, even the people who are indifferent to Donald Trump -- like myself -- are very aware of him, and the important role he is currently playing world affairs. Donald Trump is a disrupter, a challenger, a social non-conformist. He often does much more harm than good, at least in the short term. Nevertheless, people tolerate him, at least up to a point, because he is perceived to be interesting and useful, at least, at times. He rather perfectly matches Elon Musk's silicon valley ideal of "moving fast, and breaking some things." That's exactly what Donald Trump does, all the time. In a broader historical, and philosophical sense, Trump may be seen as a kind of personal example of the dialectical method, as described by Hegel -- thesis, antithesis, synthesis. Present a strong position, provoke other contrary positions, achieve a meaningful, useful practical reality between them. This is a very confrontational, competitive approach to life, but, certainly a very common one. And, at least at times, anyway, it seems to be somewhat effective. Are there other, better, approaches to life, that are less competitive, and confrontational? Well, supposedly scientists have their "scientific method", which generates systematic progress through controlled experimentation and public discussion. However, when we look closely, we find that progress of a meaningful, practical type is rather thin on the ground in professional science, despite the frantic claims of scientists to the contrary. Many if not all world religions claim wisdom and progress are possible through worshipping their own particular divinities, whatever those might be. However, all major religions disagree on what those particular divinities are, exactly. So, we have Donald Trump, playing the fool, babbling incoherently and getting attention, and people scratching their heads over it all, and trying to figure out what it all means, after all. By this stage, just a few months into a term he may, or may not, be allowed to finish, Trump appears to have largely given up trying to do anything at all, and is mostly just babbling. Almost all his executive orders have proven so totally impractical and illegal, that they have been completely rejected by the courts, and his Republican Congress may be unable to pass any legislation at all, it is so totally confused, and out to lunch. Likely, taxes will go up massively in the US this year, precisely the opposite of what most Trump voters were hoping for. If Trump is sent to prison -- as seems quite possible -- what will we have learned from him?
