Non-contact approach for measuring AC VAC/I and PF

Nonsense. Utter nonsense. Sorry, but that's what I think.
If anything engineering is more professional than it ever was.
In the 1980s, electronics was not regularly taught as a degree subject. People either had a physics or science background, or they had a regular engineering background, and picked up the subject from experience, from mentorship by others or just by breaking things until they worked.
Nowadays, if you were to do a survey of my colleagues, I would only find one person there who doesn't have a degree in engineering, and that's the managing director. Everyone else there has a relevant degree to their subject area. Engineering is practiced as both an empirical subject (from experience) and also as a body of knowledge to refer back to. It is a highly professional subject area.
This is why things like cars and electronics and the like have never been more reliable.

That was true maybe 10-20 years ago, not any more.

30 years ago, to perform music, we had to know the notes, have talent and training.
Now it's enough to roll the mouse on the table. And we can't tell the difference anymore.
When non-professionals start building bridges, flying airplanes, and control nuclear power plants simply because someone gave them a cookbook and a set of spices, you'll remember this post. We are close to it. :)
We still do not give freedom to drug traffickers (although it is also changing), but we rejoice in the poisoning of all spheres by unprofessionalism. This is incorrect progress in my opinion. :-//

Well, this time was the other way around, that's why I was enumerating the specs/features Arduino has today. It all started as a project for kids, then things changed, and now Arduino is developed mostly by professional programmers.
Music, drug dealers and personal feelings are valid arguments for a rant, not for technical evaluation. I understand such arguments as "I'm still very attached to my own biases and opinions, and not willing to reconsider".
OK, won't argue with somebody else's feelings, but please don't bash at Arduino, only because you think it is still like it was 30 years ago. Arduino has changed. Now it has libraries with better code quality, and portable across many MCUs, so you won't get locked to a single vendor. Arduino today is almost like Linux, but for microcontrollers.

For a Proof of Concept option, the Arduino is great. You could have a solution running in days if not hours. If you then want to invest the time and money into making a proper bit of hardware you can.
The places I visit I get to see lots of this. I have seen some systems where it was decided for the ease of repair etc. that using a standard off-the-shelf unit was better than a custom project. This is common for the Pi and the Arduino units. They are not perfect but there is a large network of people to ask about issues you come across.
So,

Looks to be actually a good option to try, or at least emulate.

Your colleagues didn't have an Arduino, they had to go through science. ;D
I'm trying to explain something else, you didn't quite understand.
When a future engineer breaks something, studies subjects that seem unnecessary, he does not get a universal hammer, he gets skills.
But when a programmer doesn't have to break anything himself, he can just write include from the very beginning of becoming a person, this is a bad way. But this is already happening in the modern world.
After all, you will not make a forecast of the development of the food industry by looking into your refrigerator.
Iin the 80s would not have believed that a child could do facial recognition at home. :)
So you don't believe that engineers will forget the basics in other industries.
Maybe later, but vector is like that - business and money prevail, engineering beauty recedes.
Programming has very low capital investments and is as mobile as possible. Therefore, we can see a trend in it faster than in other areas.
