You can still heat the water to your desired temp add the tea bags after. I don’t understand how your first point has relevance between a kettle vs microwaved cup

Yes you can easily boil water in the microwave.

The explosion isn’t a real common occurrence, otherwise you’d hear about it much more. Steam from a kettle can harm people as well

I don’t believe this to be true.

Edit: since the replies aren’t very polite, let me be more clear. This isn’t a concern. Any modern microwave with a turntable doesn’t have this problem

Neither is ‘AI’
