People seem to think microwaves are some sort of spooky exotic magic technology,

I'm a software dev, engineer, scientist. I understand that ultimately controlling for all things kettle water and microwave water shouldn't be different. But you can't control for all those things. If I spent the next 5-6yrs perfecting microwave boiling (the same time it took me to perfect kettle boiling) then yes, I could get an equivalent tasting water for tea.

But heating to 100C (you didn't read my link - cos that's not a good temperature!!) isn't the only thing affecting taste!

Tea in a stainless steel kettle tastes different to a plastic one. When I buy a new kettle I have to faff with timings to regain the perfect tea taste because it's got less limescale and crap in the kettle.

Yeah I guess it's all "tooling" but you're being pedantic.

So yeah I guess you're right to an extent. But it's also right you can make whisky in a gallon drum with added wood flavour. You can make wine in a plastic jug and have it taste the same. But it's not optimal and if there's a way that's been done by a group for a long time then maybe take their advice? I'm 100% certain that your microwaved tea will taste worse than my kettle-boiled tea.

I didn't like tea until I hit 21yo and a friend made me a decent cup. It changed my view on tea completely and it took another 5-6 years of obsessively making different teas and techniques to realise how much tea is affected by everything.

I can't tell if your pedantry is stubborness to accept you're wrong or ignorance of the wider picture that tea isn't a simple formula.
