If they do not double check their results with real people, I suspect that the machine taste testing will eventually fail.
I have seen statistical correlations used for a lot of years, but in each instance, they still need to be independently verified. The same will be true for this technology. Yes, it might enable them to do a wider range of detailed testing, but those results will only take them so far.
As always, they need to "Trust but Verify" the machines results.
Anything intended for use by humans had better be tested by humans.
Just my opinion.
