I suppose it suggests that AP software is friendly enough so even a layman can push the buttons
Well, the latest generation APs are quite user-friendly and you get a comprehensive set of measurement "presets" so you can start right away.
But to maintain a learning curve, also wrt how to
interpret the results, that needs a thorough theoretical and engineering understanding of the fundamentals. In the long end, no way around it, IMHO and IME. Life-long learning curve, I might add.
You may still become a well-versed AP operator for "standard measurements", QC, etc without it but mind you, the main analyzer core is your mind, not the AP software and hardware.
Nobody is born as King of the AP (or the underlying science) therefore I appreciate anybody, including influencers, who really try hard to get into all this and of course you will and
must make errors to learn and gain insights. The burdon of influencers is that they do this publicly real-time and therefore extra care is required to stay calm, real and down to earth. Credibility is under constant scrutiny...
