What is the future of airplanes in the airline industry?

Lets say 10 or 15 yeaes from now will commercial passenger airplanes look different than todays airliners for example supersonic or electric hypersonic

Because people say nothing has changed much in the airline industry people say todays airplanes look the same from 1990s

Should we try to avoid a layover in Abu Dhabi?

I'm travelling from the US to India on Ethiad and have a layover in Abu Dhabi - Anything I should prepare for? Will I be able to bring my laptop on the flight? I'm a (very) long haired indian man - am I even allowed in the Abu Dhabi airport? Is there extra security for layover flights? Or can you just go to your other flight like here in the States. Hoping someone has made this or a similar trek recently - trying to figure out if it is worth it to switch airlines and pay extra to go through France or China…
