Some tech talks make you question reality itself. This guy's up there presenting "Building Mobile Apps With PHP" with the confidence of someone who's never encountered a modern framework. It's like watching someone enthusiastically explain how to commute to work on a horse and buggy in 2023.
Every mobile developer in that audience is either having an existential crisis or frantically checking if they accidentally time-traveled back to 2009. The speaker probably follows this up with "And for optimal performance, we'll deploy to Blackberry first!"
