Sure, using continuous time sounds obvious, but the principle "What
Would Reality Do" feels scary, because we really don't know what
Reality is when it comes to time; or anything really, all we have is
mathematical models that work good enough, and sometimes we have two
different models that are used depending on how we want approach a
certain problem (e.g. light: wave versus particle)
I'm a game developer and I don't care to much about reality. But when
I'm not in hacking mode to Get Things Done, I do care about
composable, maintainable, and beautiful pieces software, and the way
games are developed today are IMO far from that, so hopefully FRP will
solve this one day and be efficient enough to run on average hardware.
