This is unavoidable for many companies, since the code bases are far to large for any single person to grasp them all.

Try to run your monolith in kubernetes, it's possible but not much fun. Since single machines can not longer scale at large, we have to run distributed software, small pieces across hundreds or thousands of machines in order to scale efficiently.
