I think it can be spread by word of mouth. I've already converted several friends and family over to electric kettles when they see how useful it is for coffee, tea, even for getting water boiled for cooking.

The big question in my mind is whether the electric kettle itself is the "final form", or if I'll be proselytizing the same people in ten years to get an Asian style hot water heater/reservoir instead.

An induction-friendly stovetop kettle is a pretty great option as well, for those with induction burners. I have found it about as fast as an electric kettle, but it saves counter space, and won't have to be replaced every 1-5 years. Maybe I have just had bad luck with inexpensive electric kettles, but they kept dying on me.

A holiday rental I stayed in had a boiling water tap. It's a small improvement over a kettle, but in terms of improvement there's very little efficiency gains to be had over a hot plate directly in contact with the cooking liquid.

Once you've had one you can't go back. I don't know what the losses are from maintaining the hot water but it's the ultimate in convenience.
