the Kardashev scale is a method of measuring a civilization’s level of technological development based on the amount of energy they consumed. Most people don’t count beyond 3.
1: Can observe universe around itself, maybe play locally
2: Pretty much able to look after itself
3: Got out and about a bit
4: That was a Fun Adventure
5: Pretty much able to look after itself wherever it wants
6: Observes universe around itself
Most users of the Kardashev scale refer to anywhere between 10 and 10^47 Watts. Get your scales right before arguing too much with them.
