Human engineers will no longer write code themselves as before, but will gradually transform into roles similar to architects and builders, responsible for the overall process, cost, system performance, robustness, etc.

The specific executors will be thousands of Agents.

Will this lead to massive job losses?

Short term: Yes.

The new model brought about by new productivity will have a huge impact on the old model, and hundreds of people will lose their jobs.

Long term: No.

There are many problems in the current world.

It is only due to the limitations of the current productivity level that everyone can see what the current world looks like.

AI will replace the original human beings to complete this transition.

This does not mean that the world has reached an ideal state.

Human beings will have more things to do.

The world is far from ideal!
