Yes, work. Smart contracts are designed, programmed and, if they’re done right, rigorously audited for correctness. Then you have user-facing interface and everything surrounding that as well. Look at the documentation of AAVE, for one example.
And this isn’t even getting into the protocol level (L1 or L2) work either. Bitcoin was relatively simple, Ethereum is not. They’ve spent years crafting these systems to function for PoS, L2 support, sharding, rollups, etc., at scale.
