> How long until a SHA256 collision
Very unlikely that this is going to happen any time soon.
Most modern symmetric cryptographic primitives with sizes >=256 bits are considered safe even against quantum computers. SHA256 turned out to be even stronger than expected. SHA-3 adoption is delayed in many protocols because there is no much need for it and hw implementations for SHA256 are commonplace.
