I feel complexity creep is often inevitable regardless of the paradigm or technology you use. Programmers have varying levels of complexity they can handle and the systems generally naturally grow to match the complexity that the people that work on them can support. Experienced programmers will manage to keep that complexity creep under control for longer and smarter programmers will manage to keep working on complex systems that lesser peers would have no chance to understand. But eventually, unless the software has a very clear functional boundary which is often not the case for business software, software will start to become increasingly complex and dev velocity will slow down, quality will drop... I've seen this happening at all skill levels regardless of the languages and paradigms used.
