Containers happened because nobody can be bothered to build an entire application into a single distributable executable anymore - heck even the tooling barely exists anymore. But instead of solving problems like dependency management and linking, today's engineers simply build piles of abstraction into the problem space until the thing you want to do more than anything (i.e. execute an application) becomes a single call.

Of course you now need to build and maintain those abstract towers, so more jobs for everybody!
