I think this forum is disproportionately hostile to emulation compared to the average gamer since it has a higher proportion of Nintendo fans, and Nintendo consoles are often easier to emulate, or there is more interest on it.
Either way, it isn't as nearly as big of an issue as some think. It seems very likely that some 95% of gamers will just go on to play the next Call of Duty or Overwatch, or find something new on their App Store to download, instead of buying or playing older console games, or going through the hassle of emulating them.
I don't remember who did it on the media, but someone called the likes of backwards compatibility or Virtual Console, for instance, the best feature everybody wants, but no one uses.
Besides the sort of people who spend their time on gaming forums, that is.
