I only voted yes, because I hope down the road they will use a higher bit hash algorithm such as SHA 512 or if one comes along 1024. Not to undermine ASICS and FPGA's, or upset the decentralized balance of mining but to increase the key space for private keys and bitcoin addresses to make it even harder to brute force someones address, because 40 quadrillion years is to damn short!
)sure, and I hope SHA256 will turn obsolete in a way that rig producers can produce future-save rigs, so fast hardware doesn't turn obsolete at some random we-switch-the-algorithm-day. Maybe SHA512 will also co-exist for a year or so. Why not.
