I feel it is a net negative for me. One of my hobbies has always been fiction writing. The LLM reflections of my own writing become slot machines to me for cheap dopamine hits. It's not because LLMs are good at fiction writing, far from it, it's that LLMs are good at reflecting my own writing back to me in fun house mirror ways that amuse me and frustrate me and pleasantly surprise me.

That slot machine addiction gives me a lot of perspective on what LLMs are good at in coding versus what they appear to be good at. It's easy to characterize them as "over-eager junior developers" or "powerful rubber duck debuggers" but their biases are still your biases so long as you are the one writing the prompts. A lot of the "surprises" aren't intelligence but fun house mirror versions of the same biases you input into the system.

I keep referring to their coding capabilities as "legacy code as a service" and the addiction to the fictional equivalent only underscores that understanding of LLMs. You don't write the next great American novel getting a word salad of past great novels back full of the best and worst of your own writing. You don't write the next great American software getting a legacy code jumble of past great software back full of the best and worst of your own prompting.

At the end of the day I'm still a pragmatist and using the LLMs in my programming efforts, but I don't trust them as a partner, I use them as a tool. (A biased tool that I know needs a careful eye.)
