HSR probably won’t get done and it’s not that sad at all. We have an immediate problem of not even having enough functional regular rail in this country. Upgrading out existing rail networks needs to have a higher priority than the fantasy of tech workers and vacationers easily able to get from La to Vegas or SF to LA.
Second if you are going to dream of a shiny future for human transport, why not build out hyperloop. Now that has sizzle and probably ultimately at lower cost.
