Every endeavor into a new tool or strategy comes at the expense of something else that isn’t being pursued. Every endeavor involves a tradeoff as well as an investment. And if the investment is mostly financial (which is often the case for the most “user-friendly” tools), we can be in for a rude awakening when the funding dries up, the focus shifts, or the vision changes. People who invest time and energy in using a particular tool can find themselves in a quandary when it suddenly goes away or becomes a paid service. So much of what we try to do or use in education simply isn’t sustainable in any sense of the word.
