The industry will never go away. The quarantine experiments and inconveniences will go away. Especially in this fast-paced world. Everybody has forgotten about the 737max crisis and are going about their business just fine.
I'd really like to do some of the music cruises some day (Keeping the Blues Alive, Monsters of Rock, Jam Cruise, Cruise to the Edge, etc). Hard to justify the cost but it'd be a blast. Cruises aren't going away any more than airports or travelling to China.
