I'm in my 40s and don't have a microwave oven because I don't see the point of it... when I lived in a rented apartment, I got gifted one because how could I not have one? I tried it for a few days and just didn't find it useful. When I bought my own apartment and renovated the kitchen, I didn't bother to install one.
Which can be done in an induction cooker almost as fast, with the result tasting better, and without the need of a specific appliance that takes up considerable space.
I guess, if you have one of those. Vastly more expensive and more involved to install, especially when renting. I’ve never used one because I’ve never been at a place with one.
When I rented I had a standard ceramic hob and still didn't see the point... sure, you gain some time, but it's maybe 5 minutes of unattended time where you can often be doing something else, vs. much worse taste. But I understand that with slow cookers it can make sense for other people. With induction I think it's outright pointless.
As an anecdote, in my country there is a very popular brand of supermarket pizzas, Casa Tarradellas. I never buy them but a friend of mine used to eat them really frequently. So once he shows up at my house with one, and I say OK, I'm going to heat it. I serve it, he tries a bite and is totally blown away. He says "What did you do? I've been eating these pizzas for years and they never taste like this, this is amazing, the best Casa Tarradellas pizza I've ever had".
The answer was that he used the microwave and I had heated it in the regular oven...
I have never had that issue when heating stuff up. Your pizza example is not reheating (and generally you never want to reheat anything that’s supposed to be crispy in the microwave; though not on the stove top either).
Ordinary ovens also do that alright. Takes 20-30 minutes instead of 2-3, but that just trains your delayed reward system a little. Also, don't use a plastic container.
They do a lot more things though, which microwaves don't. Pizza, for example, has to be cooked properly, not with a microwave. If I can only have one, I'll take the mini conventional oven.
The best tasting (and also quickest) corn on the cob is done in microwave. Cook the entire unpeeled ear for 5 minutes on high, cut the butt end about 1 inch in and pull out corn out of the husk. Butter, salt, enjoy!
I don’t own a microwave because I don’t mind the trade offs of other tools that do the same job. But I don’t go around telling people who find microwaves useful that they are bringing about the end of cooking and should feel bad because of it.
Maybe the real question isn’t whether the microwave is useful, but whether she wanted what it offered. That seems to apply to a lot of tech debates today too.
