Shows that a lot of people, ESPECIALLY programmers, vastly overestimate the competence of the average person when it comes to whatever they are an expert at. You may think that this person is silly - but that is tainted by your past experience of already knowing it warping what you think the baseline average knowledge level is at. And this issue would have never been solved for normal people - the only reason this barrier was ever breached for this person was due to their large twitter following. Most people don't have that luxury.
So, if you think it's hard for someone who is already a programmer - think about how needlessly complicated the entire ecosystem and everything surrounding it is for the average person. It's no wonder many people basically view anything past the surface level of computers as dark magic, and we call people good with these magical devices "wizards".
