A wise man once said: "Don't be too proud of this technological experience you've constructed. The ability to incorporate technology into a solution is insignificant next to the power of human ingenuity."
Or something like that.
OR A PEN.
PROTIP: COMMUNICATE BY WRITING WITH THE PEN.
Edit for clarity: I suppose that I deserve the hate for using caps, but I'm amazed that people think access to a sign language dictionary on your phone is a better way to communicate with a deaf person than a pen and paper. Sure the poster was able to learn a single sign that he ended his interaction with, but he could have nodded or waved to the same effect and would not be able to hold a conversation. With a writing implement he would be able to richly communicate with the driver, including diagrams for route choice or drawings of landmarks to navigate to a place he didn't know the address or name of. There are many impressive capabilities that modern technology provides us, but sometimes we get lost in thinking that they are revolutionary. There's nothing wrong with reveling in an experience, but you should recognize that it is only indulgence.
You could use that analogy for pretty much any technological innovation the past 50 years.
