Being abstract isn’t about saying nothing. It may even force you to say something more meaningful, if less informed. This way of speaking is effective because it implies you have a grand thought on a specific theme. It also delivers a judgment. It’s basically every TED talk, minus that one minute in the middle with actual information.
