Will AI Replace Software Engineers?

Will AI replace software engineers?

No.

As a staff software engineer who works with AI extensively, I can say that the fear a lot of people have is valid and understandable, but total replacement is not going to happen.

Why?

Software engineering requires decisions. Architecture, tech stack, workflow design, and many others. AI does not understand how to make those decisions, it was not designed for that, and it is not heading in that direction.

Artificial intelligence is a tool designed to improve the productivity of humans, including but not limited to software engineering, and in that realm it is the biggest jump in day to day productivity I have seen in my career. It has increased the output of software engineering by orders of magnitude, and that is what makes it so good. It is also why some people think it might replace software engineers.

Large language models, with access to the right tools and when they run in loops, are very strong and very good at improving the productivity of software engineers. They also help engineers improve the quality of their decisions.

Even with the best AI models out there, and with unlimited tokens, if you instruct one to implement a product, and I am emphasizing the word product here, not just a feature, it will get it done with the happy paths only, the absolute bare bones proof of concept. It does not know how to complete the product end to end, it does not know how to integrate it into the real world, and it certainly does not know how to architect and design the flow or how to make decisions. At best it can guess, and those guesses will always fall short of what a human can do.

That is why I believe software engineers will not be replaced by AI. AI is a tool, and a tool replaces parts of a job. It makes the work faster, more accurate, better documented, but it is not a total replacement.
