My point is that life isn't to be found on exoplanets (certainly not for long), that 40 years or 40,000 years is nothing to an immortal being, that Dyson Spheres make about as much sense as burning dung for fuel.
Huge expenses from our perspective are trivial for a powerful civilization working on astronomical timescales, not biological timescales. Maybe it takes 150 years to build their gigantic planetary scale accelerator complex for highspeed travel (it probably wouldn't if they just spin up more workers or use advanced construction methods). Maybe it takes 1000 years to build a dark matter refinery. Why would they care? They have billions of years to work with.
Our knowledge of physics is overrated. Still no fusion power! What could we achieve if we had a particle accelerator that ran all the way around the world? What could AI discover if given hundreds of years, billions of terawatts, giant computer complexes the size of countries? This is mindboggling sci-fi stuff for us, it's boring and primitive for a powerful civilization.
No, all we know is what we can see. And we can't see 95% of what's out there!
