Java apps! ducks But seriously folks, I'm curious what went wrong there. The JVM these days is very fast, runs everywhere and comes installed by default on most operating systems. I was still a student during the java hayday, but the only downsides I vaguely recall were poor UI, poor security and poor speed. The last two have been fixed and the first one seems very fixable. Furthermore, you don't have to write apps in java anymore. It just seems like there's a lot of untapped potential there these days.
