The Hardest Part of Software Was Never Writing Code

Why architecture and validation matter even more in the age of AI coding agents

Everyone seems to be asking the same question lately:

Will AI replace software engineers?

I don't think that's the right question.

AI has become remarkably good at writing code. It can generate functions, refactor modules, execute shell commands, fix failing tests, and iterate on its own. Tools like Cursor, Claude Code, and GPT-powered coding agents have transformed what day-to-day development looks like. Work that used to consume an afternoon can now be finished before you've had time to refill your coffee.
