"tea made at 66 degrees?"
The recommended brewing temperatures in °C for the varieties: Black Tea: 93-100,Green and White Teas: 71-82, Oolong Tea: 82-93.
Electric kettles(jugs) with selectable temperature are available which make using the recommended temperature easier.
This assumes you aren't indulging in the barbarity of adding milk. Might as well add milk ice blocks and boil the buggery out of the hopefully cheap substandard tea leaves. Instant powdered black tea (shudder) was once a thing which I imagine you could add easily tepid water or heated milk without compromising the taste. ("brown fluid that is everything but drinkable tea!")
I cannot imagine the Japanese tea ceremony with a tiny robot puffing over the tea although I can imagine their producing an AI enhanced robot geisha but I suspect tea making wouldn't be high on the list of its functions.
Like most of the "also rans" at this show the product is an overelaborate example of poor engineering and design. If you wanted to cool tea etc more rapidly you might use an aluminium mug with a heatsink or include a usb-c powered peltier refrigeration in the wall and base of the mug.
Or just be patient and dunk your biscuit while waiting. Tipping your hot tea into the saucer to cool it and drinking from the saucer is apparently rather frowned upon. (Apart from Hyacinth Bucket (Bouquet) who uses a tea cup and saucer?)
