This is mostly self inflicted though. We create complex deployments with the promise that the incremental savings will overtake the upfront costs when they rarely do (and the hidden complexity costs).
So it seems AI will just let us stretch further and make more accidentally complex systems.
The value of automation ("complex deployments") is not only incremental cost savings (ie because you don't need to do the work over and over), but also the reduction or outright elimination of human error, which especially in the case of security-sensitive activities like deploying software on the Internet can be orders of magnitude more costly than the time it takes to automate it.
