I think what's really interesting about this that most readers seem to overlook is the claims about subluminal warp drive, which is practically realizable in a way that the science-fictional faster-than-light case is not

Any subliminal system that avoids Doppler shifting everything in front of your ship into hard X-rays is going to be a big deal. Also help with micrometeoroids.

Everyone papers over these very real problems like they’ll just get solved. But if you can keep your ship at .05c while moving at .4c relative to your starting point that’ll be a huge deal.

Baby steps! Every step is worth it. I know the math and science doesn't support me but I'm convinced FTL is possible and that the universe won't die a heat death.

The universe heat death theory makes me think of comics where people extrapolate the data they have while lacking other critical data. https://xkcd.com/605/

The heat death theory assumes life has zero impact on the universe.
