It's likely that the nm number will continue to get smaller, since the node name is marketing at this point, and isn't related to any physical semiconductor measurement anymore. As for quantum tunneling, it is likely to be mitigated or exploited at some point. If not, maybe we'll have to use something else, like gallium arsenide[0] instead of silicon.
