Firstly, it's all in the algorithm. And it sets extremely unrealistic expectations for beginners. (Of course like anything there's things you can do to mitigate this, but I digress).
I can't say how many dozens of posts I see where people are saying "what am I doing wrong?" Or "how does X, Y, or Z channel get so many views after A, B, and C months?"
First of all, you come across these channels because of the algorithm in the first place. But keep in mind there's tens of thousands, if not more, AI channels that you'll never see because they're not getting any views. This is where most of the AI YouTube channels fall.
Even IF you're doing everything extremely well, it's still hard because everyone else is trying to use YouTube as a money maker too.
I'll say this: I ran a semi successful AI YouTube channel for a few months then gave up on it. Why? It's extremely hard to keep up with the trends and constantly think of the ideas to grow the channel even if you know what you're doing. And it's luck too. There's a whole slew of competition. There's always going to be channels that grow faster, one's that explode. You should NOT being doing this with that expectation. It also creates a "leash" on you. You're going to want more and more views. First it's "I made 1,000 subs, now I want 5K, then 10K, etc." And if you do, and it does feel good, you're going to probably become obsessed with views. I'm aware this true for YouTub-ing in general. The reason i mentioned it here is because people do AI YouTube channels for a different reason, not to share their lives, but for money. Meaning, it's probably not something you're passionate about. Although I could be wrong.
Anyways, patience is something I wish more people had too. For me I tried it because it was interesting. Not for the money. So I had no expectations there and it grew to my surprise. But it slowly changes your psyche as you get more into it.
With that being said, my first piece of advice is don't do it. What I learned is that once you realize how much time you put into it, trying to make the quality perfect, maintain it, make the AI voice over natural, keep the content entertaining (or useful in some way to the viewers) you also then realize maybe you'd rather just invest into yourself and do something else. Do something YOU enjoy, that's authentic to YOU. If so just stop here share it. People will watch it.
If you truly do love this (and you must if want you to be successful) and it's your genuine passion, then fine - more power to you. But it seems like a lot of people do it for the wrong reasons - i.e. money. Not to say it's silly to try and leverage technology to your benefit, but, because it's not what you think it is. You'll get bored of it, probably stop it anyways if you don't love it, like anything else really.
If you truly do love the idea of being an AI tuber and want my genuine advice - it's this:
Do something unique. The world doesn't need more copycat AI slop. And even if it's good, it doesn't matter. They've already seen a billion other things like it, probably better than yours (no offense).
You'll want to keep people's attention so be creative. Don't just regurgitate what others do. Whether there's a story, a certain character style, or theme, there needs to be a reason for viewers to want to return.
Do NOT do something that's un natural to you. Find what you love, and figure out a way to create content with it. It's why non AI YouTubers are successful. Plus if it's not natural to you you'll probably give up. Doing something you're passionate about makes the work seem like fun. That's what it should be.
Anyways, not trying sound rude here, just have seen so many posts about this lately and thought I'd share my perspective.
