Haha so long journey. Well personally i like the shows like vsauce and his whole party, eventually he turned a bit more money focused and make partnership with lower quality resources howtobasic channels rotfl. But generally to have something like that wide area of shows topics and sharcasmic jokes well generally I suggest to make something similar in your style, unexpected how many people interested in things like math , physics , religion/theology bit of everything... We may still bit far away from the world shown in idiocracy movie...
I am about 30 and fortunately developed paralel processing for audio so during my work can listen majority of documentary, science videos , or voice books of course... But my favourity of all topics are environment biology technology and bit of everything about science and eventually philosophy...

And one of the things i am all the way different from different humans who absorb things like these I don’t / didn’t like majority of the thinking of stephen Hawking overhyped...

If u make some shows i would tune in lol
