I feel like this article is completely backwards in its premise. It is confusing labor intensity with cost. Software used to be an incredibly labor intensive industry with extremely low automation costs. The cost of running a computer and its associated development environment is so low that it is a rounding error. While you might pay a monthly subscription for an IDE, even that cost barely even registers and it only assists the developer's productivity by a double digit percentage at most.

Here is an illustrative example: Copy paste and traditional code generation features in IDEs (automatically generating getters, setters, hashCode, equals implementations and so on) only reduced the typing of boiler plate code with low cognitive load. This type of code was never very labor intensive to begin with, because it can be reduced down to the act of typing. These tools have made writing code cheap decades ago and you could have written a similar blog post about these tools, because the premise fundamentally misses the actual point.

The cost of writing code has never been an issue in this industry. Software developers don't spend their entire day writing code the same way car mechanics don't spend their day screwing bolts. If you send a car to a mechanic, the mechanic must first diagnose the issue. In some cases the preparatory work is all of the work.
