How long do you think Minecraft's popularity will last?

I see a lot of kids playing other games. But I think because there are so many games out there, it's hard to make one specific game stand out, especially when many people have different tastes. League of Legends has never really had much of a chance against Minecraft even though its popularity has soared on Twitch, and I think that's because people don't watch Twitch as much unless it's for some sort of competition event. And Fortnite seems to have quite the popularity, but I think because it's primarily a battle royale game, it doesn't cater to as many people as Minecraft. I think Minecraft will remain a behemoth until something revolutionary comes along that also includes the versatility of Minecraft and much more.
