But at the same time we rely on TCP/IP which uses a hash (checksum) to detect back packets. It seems to work well in practice even though the hash is weak and the network corrupts a lot of packets.
Lots of machines dont have ECC ram and seem to work reasonably well.
It seems like these two are a lot more likely to bit you than hash collisions in MD5. But Ill have to go read the paper to see what Im missing.
