How to make Minecraft less boring.

I really think this could bring back Minecraft. And it's very simple. All you have to do is fix progression, it's messed up. For example, the player improves and improves but the mobs stay the same. It gets too easy. To fix this you could make it so when you defeat the ender dragon more advanced mobs spawn and netherite doesn't start spawning until it's defeated, or when you get a full set of netherite armour even more advanced mobs spawn, and just make the game a bit harder after a milestone is completed.
