Ask HN: What game (industry/company) should I be playing as a young adult

I am considering what game I should be playing when it comes to my career.I recognise choosing the right game (i.e company or industry) is more important than how hard that you work. So, I am trying to choose the right idea to put effort into for the next 10 years of my life.

Strenghts:
1. Devops/infrastructue work at a major tech social media company when the infrastructure team was just 20 people.
2. I have a nack for asking very good questions. So, I started a youtube channel to interview people in tech. I am making content and plan to continue for the next 10 years.
What interesting tech content do you think is missing from YouTube?
3. I have lived in 3 continents and 4 different countries.

Interesting industries:
1. Material science to support space efforts
2. Nuclear energy
