• Answer questions (with references) about source code and documentation
• Add clear-bounded features to a pre-existing codebase
• Transpile between programming languages

Stuff I can do myself perfectly well, but the results - after postprocessing - are indistinguishable from me having done so. Even when accounting for everything (including hallucinations) the time savings are real: Renewables-powered electricity is cheaper than my attention. By a lot.

Caveat: This only works if you're already a domain expert and if you do it exclusively for too long, you might be at risk of ceasing to be such an expert. Don't use it to try and do the thinking for you.

I handle so many text files in my job and LLMs help make the scripts for me to handle these text files. I know it is important to at least know stuff like regex but I am not a superhuman. It is difficult for me to heavily specialize in scripting while also specialize in the technicalities of my job. To help show why it is difficult to specialize scripting, I work with hardware description languages which have a different syntax from scripting languages. Handling different languages causes confusion on the proper syntax even with a basic if else statement because the syntax is different between languages.

Aside from this, it can also help me automate describing what the sequences I created in the file for easy documentation. I just have to instruct the "patterns" it needs to look for. I just need to proofread the output and do minor fixes.
