Arguably so, in that app-level data has a richer set of failure modes than even highly-complex physical materials and flows, but I don't think that detracts at all from your main point.

The linked article used the word "unknowable" to describe the failure modes in a complex datacenter. They're definitely "unknown," but it's way too early to just give up on figuring many more of them out.

If a CTO says "it'll cost $50B to reach less than 5% unknown failure modes," that's one thing. But if a CTO says "yeah, the faulre modes of our critical infrastructure are unknowable" they better start looking for a new gig.
