Using a mid-IR array with sub 10nm resolution is anything but an engineering path. Tech like that has never left the lab afaik.

Fair point. That's why the paper labels it Tier 2 (near-term research) rather than Tier 1 (existing instrumentation). Tier 1 — scanning probe read/write on a single sample — is the immediate validation target and requires no new technology.
