I have a Panasonic "Genius" microwave that I actually like quite well. The "inverter technology" does seem to cook more evenly than previous microwaves I've had, and the "air fryer" (not really) mode works very well for a bunch of frozen things that should be a bit crisp on the outside (e.g. samosas or taquitos). Day old fries often come out better than they were when fresh.
Is it an amazing indispensable life-changing invention? No. But does it suck? Also no. The premise of the article is seriously flawed, and comes across as somebody who just didn't like anything but old-fashioned stove cooking (probably by someone else) in the first place.
