lot of other and better versions of consensus algorithms
you first have to prove that there exists a consensus algorithm that is actually better than PoW then discuss why bitcoin is not choosing that "better" algorithm.
so the real question here is "why do you think other consensus algorithms are
better than PoW?"
I have been doing research on why Bitcoin is better than other cryptos and I came across many other algorithms for consensus that seems to be a bit better than PoW theoretically! The most important of them seems to be PoS.
PoS:
It gives power and voting rights based on Stake system.
It has no mining rewards which removes the ongoing war for mining the block earlier than any other miner.
It has lesser energy consumption for its functioning.
