I use Go for work and Rust for personal projects. I use Rust because it makes programming fun. Programs just work after they compile, and often are fast with minimal effort spent optimising. If that sounds compelling to you, then it might be worth learning and getting over that initial learning curve.

But if it doesn’t, that’s fine too. Go is a great language that works well in many domains. You won’t have trouble finding work in Go for years. It’s unlikely that you’ll have to solve a problem at work that can’t be solved in Go. You’ll be fine. Don’t guilt yourself about it.
