To get the private key, you’d need to reverse the keccak256 hash and do the
inverse of elliptic curve multiplication (discrete logarithm). Both of
these operations are known to be computationally infeasible.

Now that can calculate the address from the private key, why can't
calculate the private key just using the reverse calculation process from
the address?
