I see that happening now, and I don't think it's a problem unless the observation-generators want to go way beyond their results. If I do a plankton sweep, mush the catch and get a spectrum of (say) 28s, I might be able to say something intelligent about how that plankton sweep differed from another in some other place. But not a lot. And if I said something like 'dominated by chaetognaths' based on 28s, I'd better have done whole-animal counts on at least a subsample of the sweep. The first claim would be based on inference, while the second route takes me to the facts.
Same with blind barcoding in a tropical forest. 'I caught a something and the libraries say it was a fly closely related to X but in fact a new species.' Repeat that with another specimen, and repeat that, and repeat that. What have you learned?
The observations you see being generated which aren't attached to names have very limited usefulness. Hand them over to taxonomists, together with the vouchers, and we'll tell you more, often a lot more, because taxonomists are usually taxon specialists who know a great deal about the taxon. We aren't replaceable.
And please go easy on the hyperbole.
