Change domain or be an expert in the current domain?
I have an opportunity to change my current domain (Infrastructure/Developer Experience/Tools/DevOps etc) to Ads (ML engg - building infrastructure around ML)
Wondering what to do? Is it good to change domain to understand the set of problems different domain has or stick to 1 domain and be an expert on it?
How does this affect career growth? Which domain would be good in the longer run? Especially for FAANG?
