Been using this font for about 6 weeks now, and from my experience i actually found this super readable and easy on the eyes. Had to just make font size slightly larger in VS Code, but very happy with this.
We work, live and operate in a complex environment and I think if we start viewing the organisation its projects and the environment in which it operates more from a systems perspective we may realise that in fact, it is truly difficult to make accurate predictions given the non-linear behaviour the system exhibits that results from all the information flows (or lack thereof), interaction of parts and other dynamics such as markets, human energy levels/mood, etc.
I really learned a lot from the book called Thinking in Systems and nowadays I can't help to look at projects, from within the context in which it operates. Definitely recommend the book for somebody wanting a bit of an introduction to that mental model.
Physical books are the ultimate dumb tool: No need to charge; no notifications; can take notes if you like; and fantastic life span if well looked after.
