If you look at the data, software jobs are growing far faster than new graduates in computer science. A quick google search just found well over 250,000 open positions in the US, with about 50,000 new graduates per year. I'd bet we have decades more of high demand and high salaries for people with CS degrees. I wouldn't be surprised if low-code tools get good enough to power many websites though, so I wouldn't be quite as bullish on code-camp graduates seeing the same growth in salaries.
