Agree about the long distance being subjective. I live abroad and have a job so for me it's not an option to use 2 days of my holiday time just to travel back and forth for one visit home. So I definitely mind that it takes considerably longer.
Well 3000 km is about 2h30 by plane. A train that goes 180km/h without any stops will still take 17h. I agree all the check in and travel to the airport definitely sucks, and I'd rather board on a train any day. But even with that nuisance, a regular plane going a typical cruise speed of 900km/h will still leave trains in the dust for anything farther than say 2000 km and make it worth it.
I don't think train can compete with a long distance means of transportation that is
1- equally or less time consuming.
2- works very similarly across countries.
3- only needs infrastructure at the start and end stops instead of for the whole journey.
What we need is to figure out a way to use less polluting, carbon neutral or non-polluting fuel for airplanes, and less of it with more efficient designs.
We need to take responsibility for what we do. "Just doing my job" has been an excuse used for centuries to do atrocities.
Oh no! The company is going to miss so many important aha moments that only happen spontaneously on coffee corner chit chat among the "how was your weekend with the kids and the wife". To think of how many technological breakthroughs we're going to miss...
