Low effort streaming seems to be the easiest, podcasts are usually themed and edited, whereas just opening up a youtube and pulling in superchats seems super chill if you are able to yap and network.
The issue is if you can yap, but not network, no matter how funny/quality you are, you'll never get anywhere, just like irl, networking is the key to career growth fair or not. In streaming this is probibly double.
Starting a stream without networking skill isn't impossible though. If you start by making short 9-min maximum videos on a popular but lesser covered subject, just reading the related news articles / reacting to videos / playing a videa, DAILY, will eventually pull in enough regular viewers to support a weekly stream, which will grow into a daily stream, that then can be coasted on since chat will just guide the whole thing. Not impossible, but certainly a grind to get started. If you can get your claws in, even a middling streaming job appears to make bank.
I have also watched many lowtier guys struggle for years to get going, like 90 viewers for 7 years slow. So I certainly don't think it's as griftastic as plastering a blogspot with google adsense and just muscling the hell out of the seo, which was fairly easy before bots destroyed google search by doing just that en mass.
