I was talking about how physicists will understate how difficult things can be. 'Feels tractable' is physics-speak for: a possibility exists to get there though it may require more teachers than there exist on the earth and more compute time per student than there are transistors in the solar system for the next 1000 years. Anti-gravity would be 'tractable' too as we can see there must exist some form of it via Hubble expansion and then it's only a matter of time until a physicist figures it out. Making it commercially viable is left to icky engineers. Things that a physicist don't think are 'tractable' would be time-travel and completing your thesis. To be very very clear: I am somewhat poking fun at physicists. Due to the golden age of physics, the whole field is kinda warped a bit about what they think is a doable thing/tractable. They think that a path may exist, and suddenly the problem is no longer really all that much of a problem, or rather 'real' problems are in figuring out if you can even do something at all. 'Tractable' problems are just all the 'stamp collecting' that goes into actually doing it.
