My day to day assumption is for nearly anything I want to do, someone else in the relevant domain has already done the deep dive and it's a variety of premature optimization for me to over invest. If it's important, or my domain, or something interesting, sure, I'll dig in deeper. However, we live at a time where vast expertise is a few clicks away, so I find it's usually more valuable to know how to find and analyze someone else's solution than to create my own.
