How Space Industry Could Reach Kardashev I and II
FWIW, from Wikipedia.
Kardashev I civilization (planetary) is able to access all the energy available on its planet and store it for consumption.
Kardashev II civilization (stellar) can directly consume a star's energy, such as through the use of a Dyson sphere.
Kardashev III civilization (galactic) is able to capture all the energy emitted by its galaxy, and every object within it, such as every star, black hole, etc.
Pretty wild!

if we double the industrial production in outer-space every 12 months starting from some initial seed in 2030 then we hit Kardashev I by 2064 and Kardashev II by 2098. If we take 24 months for each doubling, we still hit Kardashev I by 2096 and Kardashev II by 2165
