Read the second to last slide. What we need now is *imagination*. You assume the need for new software is fixed and that AI is going to satisfy that need with fewer humans (lower cost), but by lowering the cost we can increase the supply of software!
That means software engineers better start getting creative. If you think your job is to wait for a PM to assign you a well-written researched ticket, you're done. Your job is now to figure out how to make these machines (computers) do whatever we need them to do safely, quickly, at scale, and correctly by applying all your knowledge of computer science and the engineering field of software engineering to an AI prompt.
This doesn't scale, because like in a factory that gets replaced by robots, or in a supermarket with self checkouts, not everyone gets to save their job, regardless.
Also, the increase in output is meaningless when the amount of customers doesn't scale in similar size.
Then there are the constraints of physics, there are so many humans in the planet that actually want to pay for a specific product, or consulting services.
