It really depends on what you are doing and what tech you are using. I use it to teach me or build out ideas quickly or solve for complex issues. Mostly these days I use it as a memory aid or to bounce ideas off it. In my job I have to move quickly and stay focused as I'm driving improvements to a tech stack that reaches across four verticals, each having their own quirks and tech stacks. It's great for jogging my memory and helping to flush out ideas and approaches that I then bounce off the dev teams. Super helpful.
