This post is about a little different topic than my normal topics of software engineering and investing. The beauty of having a personal blog is that I can write about any topic that pops into my head. This post is about potential dangers of contacting extraterrestrial civilizations before we are ready for such adventures. I have always been interested in space exploration so this topic is near to my heart. I am also in the process of reading the Three-Body Problem by Liu Cixin which is an excellent science fiction book, and very closely related to this subject. Highly recommended.
