Huh. Your statement was probably hyperbole? But just back of the napkin:

If we use about 20 TW today, in a thousand years of 5% growth we’d be at about 3x10^34. I think the sun is around 3.8x10^26 watts? That gives us about 8x10^7 suns worth of energy consumption in 1000 years.

If we figure 0.004 stars per cubic light-year, we end up in that ballpark in a thousand years of uniform spherical expansion at C.

But that assumes millions ( billions?) of probes traveling outward starting soon, and no acceleration or deceleration or development time… so I think your claim is likely true, in any practical sense of the idea.

Time to short the market lol.

He said light cone, so not all of the energy of the sun.

The sun a few minutes from now is in its entirety within our light cone. https://en.wikipedia.org/wiki/Light_cone
