We have seen similar things in other industries as well.
I had a chat with a friend and he said it very nicely: I have all instruments to build my own desk, but at the end I go and buy it. Even though there are tools to automate the implementation, and people can do it themselves, there still will be people who will need manual implementation. Banks, military, government projects, the level of security and confidentiality is so high, that they can't switch to AI at all.
I strongly believe that the work will drop, because less people will be needed, and the expected quality will be higher, because manual labor is expensive, but it will remain. Like in car manufacturing. You buy a car and pay for it, but there are expensive hand-made cars that you can buy, and they are highly customized, with personal attitude toward the clients. Manual software implementation can go the same direction as hand-made cars.
