> Simple web apps, the kind you're describing have never been difficult, they were never what kept SWEs employed.I'd say the first part is right but the second part is statistically incorrect. I would even expand from "web-apps" to just about any kind of software, especially "business software" -- very little of it was ever too difficult.
Now the following will clearly not be true for all cases, and the boundaries are very fuzzy, but generally a huge part of software development has always been the relatively straightforward translation of high-level requirements into code. Crafting the high-level requirements was typically the challenging part, but that typically was done by the more senior devs / architects, whereas the actual implementation was done by more junior / mid-level engineers. And there were typically multiple junior / mid-level devs for every senior dev, say 3:1 or more. As such, it is correct to say that the simpler aspects of software development were what kept most SWEs employed.
Now AI has completely usurped the lower-level coding work. You as an expert dev are definitely getting worth more than ever with AI, but that's because you single-handedly can now do what an entire team used to do. You may even get paid much more, but that is eventually going to be at the expense of a bunch of other people who are not required anymore.
This is why people are seeing "jobs apocalypse" written on the wall.
