how is your 3 word unique adress better than a unique GPS coordinate ? It is sexier to read than a list of numbers but also less precise. I love your project but couldn’t answer that question when my teacher asked after I mentioned @what3words in class
3 word addresses are as accurate as GPS but more memorable, easier to communicate (with people and machines) and less prone to errors | Read these out to your teacher and ask them to repeat them back to you
