  1. Gravity is too low for humans to live without complications
  2. Atmospheric pressure is too low to go outside without a pressurized suit.
  3. No magnetosphere means dangerous radiation abounds.

I feel like all of these can be engineered around, but I guess time will tell.

The article has the same energy as that one article about man never flying published in the 1900s.

Forever is a very long time. It’s unlikely to happen in our lifetimes though.
