That's not the direction it is taking. It will be more like 1 highly paid developer doing everything himself. When I started working, it took a team of testers, a team of dba, and a team of sysops in addition of the developers to build anything. Nowadays, no only the development team is smaller, but the sysops, dba and testing are the responsibility of those developers too through automated tools. On the client side, there used to be BA and Testers, but nowadays, BA and Testers are often the same persons. The tshirt from several years ago "I will replace you by a tiny script" has proven quite true. Old job that required qualified people before have been replaced by scripts, not "blue collar" worker. A huge amount a developer entering the market could lower the salaries, but any simplification to the developer role is going to be handled by automated tools, not human.
