i think it isnt dying right now, its a game that has alot of possibilities, and games do have their ups and downs, so maybe the payer base is decreasing right now but it could increase any moment again.
it would be nice of they implemented a workshop where you can easily download and install mods. i also hope they will implement a Friends List one time
lazy really isnt the right word. a year ago they made clear they did not want to make small and frequent updates but larger updates that would take time. they initially wanted to release about 2 updates a year.
Make something what takes time to make, for example: Ethoslab is making that Nexus-thingy (a huge redstone storage, if you didnt know). if you make something big i dont think you'll get bored very fast.
