A startup launched here a few days ago that does autocomplete for the terminal. Not even all low-hanging fruit has been picked, let alone software for managing intricate processes deep within the economy or software catering to most niche interests. The global SaaS market is growing at something like 10-20% year-on-year. Developer salaries have been rising steeply pretty much across the board. When the exponential growth ends, the steady state will likely be quite comfortable as well. You can pick whichever area you have an interest in and be safe for the foreseeable future. BTW forget PHP systems, all the web and mobile apps built on top of 100s random NPM packages will require a tremendous manpower to deal with for decades.
