Ok but todos have a time cost. It takes time to watch a YouTube video or read a book or make a slide deck. Todos often have deadlines as well. You can't capture all of this in an unstructured text file unless you create your own grammar (like what Andrej showed). Even after that, you need to visualize what's in progress and what's blocked because of some other todo, and before you know it, you have reinvented a shittier version of Linear.
