great read! I'm 3 years into the language and brought it into my company. As part of mentoring other devs coming from a web background, I kept repeating the mantra, "make it work the simplest way first" then explore the options scala gives you. As long as there were units tests for the logic, the details could change. The more I use the language, the more fascinated I become. Heck, I just learned about Bottom types last week!
