Great article, though I don’t agree with everything. I suspect open source and some hand written (or at least hand reviewed) code will continue because software is inherently complex and modularity will always be more economic. In other words, AI will allow software projects to get larger, but it will never be economic (or secure) to build all the building blocks from scratch every time. Like new research in biology doesn’t reinvent from scratch all the chemistry it depends on. No doubt AI will soon be able to build using open source pieces too.
