Although the difficulty adjustments in Bitcoin are much slower than in Ethereum. The chain with the smaller hash rate is unlikely to be functional for a long time (unless new miners step up but this would be a tremendous investment). This is by design as this makes it economically unfeasible to fork the chain and suddenly have twice the amount of coins.
