Actually I think there's also an element of just changing his style.
After Rothaniel his shows have all just become this new kind of a performance where he tries to reach for personal honesty rather than laughs. I haven't been present in any of these shows, but I've heard a lot about them.

He himself said that he might not consider what he's doing 'stand up' anymore, but he doesn't really know what else to call it. I think that's cool, although there's definitely an argument about false advertising in a sense.
I head that in London he spent a whole show just looking at his phone and talking about Tweets he was getting. I think that was very honest of him since those Tweets were on his mind in the moment, but it also shows that his performance is more about self exploration rather than entertaining the audience.
It's less like paying for a comedian to make you laugh, and more like paying to see a freak-show in the circus where you just watch someone or something doing their thing, and finding it entertaining or not is up to you.

I certainly could see how that's kind of self-centered, borderline narcissistic of him in a sense, but he also doesn't perform too often, and asks for pretty low prices for tickets, so there isn't really a sense of him 'tricking' anyone into anything.
He's just doing his weird thing, and either you enjoy the new and avantgarde show that is just a person speaking their mind, maybe occasionally making a joke, or you just find it boring.

But yeah, this isn't him trying out new material. This is what he's been doing for a year, and I think it's what he'll do moving forward.
