The “cloud wage” story could be very compelling in such situations, but it will likely lead to a lot of issues with the more complex systems. Someone has to be the true “architect” and own the successful evolution of the software/business.

If you only have automation or low-end jobs, you are going to lose the ability to make transformative/revolutionary moves. You will still have the ability to refine existing processes, but there are definitely diminishing returns to consider.
The other item that’s also glossed over is sheer productivity - when dealing with more complex issues, experienced developers are a lot more productive, so your $15/hr can easily turn into 10-20x more hours with the wrong experience choice, in the end costing you more.
Hate to use a cliche, but “the right tool for the right job” applies to software too.
