It's good for what it's good, and bad for what it's bad.

If you only use it for what is good I would suppose it would be easy to be more productive. Sometimes is faster to ask an LLM than trying to surf through pages of SO "repeated question" to get an answer.

I use mostly for things like that, questions, translation between languages (for instance having some working code in one language that you want to quickly translate to other language), boiler plate of well known algorithms and functions.

For full programming development I've no luck to make it work. And trusting it to refactor all your code would be something hilarious.
