ㄴ다는 것 같다

apparently, it seems they say

A reported statement in "-ㄴ다는" (that they do, that they will) wrapped in 것 같다 "it seems". The speaker is passing on something they heard without vouching for it: apparently about 400 billion a year comes up, it seems they're told to do it with Minecraft commands, apparently something's been installed temporarily, apparently the US is saying no. The hedge is about the report, not about the fact — compare plain -는 것 같다, where the speaker is hedging their own guess.
