Once I have proper microwave , I possibly don't need any other cooking tools any other cooking utensylia anymore in life.

I cook and warm everything , including cakes and grilled meat .
But that is me lazy cook with iron clad stomach.
Obviosly there is still place for improvements and on my with list is
THERMOMETER.
One contactless and another on stick to get inside food.
With smart programming to allow set and observe desired temperatures.For example the main problem with cake is burning from inside when baking, cooking.
Simple thermeter plug in inside will allow to avoid temp rising above one setup and safe in the middle of the dish.
