Taro Founder Background (YouTube and Side Project Hustlers) How Can We Emulate as Content Creators?

I am an educator and have been watching Alex's course about projects, which are impressive also side by side with Rahul, who I see has a large following on YouTube, I can definitely tell this was a co-founder match that created Taro!

I am thinking about my next platform and have been told to create a podcast or YouTube channel, however my content is harder to create (technically complex to talk about 3 different parts of the tech stack). My co-workers and friends who have 20K subscribers on YouTube spend a good amount of time just to create tutorial videos or livestream on Twitch that talk about the same topics, but something I find extremely rather time consuming and exhausting. Even without teaching someone how to code a project, at a high level talk/presentation can also take many hours to create a powerpoint and I'm finding that wanting to have a blog post/Substack on this is easy, but another video on top of that, is even more time intensive/energy wise to edit graphics etc., but subjectively easier than giving a workshop tutorial.

I am trying to figure out the cost-benefit analysis of energy/time this takes vs. simply having content that is high level overview (talks I have given on my technical expertise, which is mobile, AI etc.).

How does Rahul come up with his topics for YouTube and regular posting cadence that helps him grow his user base, based on past content/projects he has created similar Alex talking in his course about how we built his projects? I am finding that either way, it's a lot of work, but may less work than going line by line to explain install fest and actual workshop tutorial on how to build an app.
