Mojo might be the biggest thing to happen in programming for decades
The two biggest things that have happened in programming for decades are:1: StackOverflow2: ChatGPTNothing else comes close.  Certainly not any new language.WHY these two things are the biggest developments in programming is because they help developers solve problems and learn new things from a global accumulation of programmer knowledge.If there was a Nobel Prize for computing then both StackOverflow and ChatGPT would be deserving of it, or the people behind them anyway.
