I used to be a lot more pro direct Democracy until I went through the whole Brexit thing whilst living in Britain.

One look at the polls over there right now on the question "Is Britain better outside the EU" compared to what it was back at the time of the vote, should answer just how well informed the voting decision of a large percentage of people was back when they did cast their vote.

Looking around after that, I started noticing how most people will not abstain when they fell they're not well informed enough to make a decision but instead tend to feel they have to make a choice even though they're ill-informed (or worse, have no clue they're ill-informed), plus if there is one thing the Leave Vote in Britain showed me is that ill-informed voters are way easier to push to make a certain choice purelly with appeal-to-emotion and other manipulative non-rational "arguments" than the well informed.

Representative Democracy has massive problems, but at least those people do it as their work (so do have the time to dive into issues and have easier access to experts), and I suspect that most of the problems of it can be solved or ameliorated by improving the process of selecting representatives and maximizing the independence of the Judiciary Pillar of Democracy (you see the worse kind of stuff in places with Justice Systems which aren't independent or are weak, and/or voting systems mathematically rigged to promote a Power Duopoly by giving more representatives to larger parties).
