> As soon as recordable CDs were affordable, I switched completely, and never looked back.

Cassettes were good for mix tapes, but once their were CDs and MP3s I never really looked back.

> Do you still use a kerosene lamp when you go into your barn at night?

It not quite the same comparison. Not sure about a kerosene lamp, however a kerosene/paraffin stove does have it uses.

You would be surprised what people are using. I spend a lot of time walking/cycling up canals and people are using wood hearths and similar to keep the boats warm in the winter. Wood is literally everywhere along the side of the canals and so it is literally free energy.

Some of the boats have solar panels, generators, full internet but quite a few of the boats only have relatively basic amenities by today's standards.
