nice post, what a great change that happened n such a short period of time- the world is moving fast- u don't know what to expect next- but with all the things ai is making it's indeed a milestone n our history that will change the world like never before, so i think maybe n 2-3 years many people will have ai personal assistant that will do the booking & such tasks, & i think maybe n less than 2 decades hyperloops will b available for ultra fast travel. looking back how life was just 15-20 years ago it looks like ages like a historic movie that next generations will have hard time believing how life used to b so different just like how at some point there were no ai, drones, self driving cars, streaming, smartphones, internet, mobile phones, gaming consoles, computers, spaceships, tvs, fridges, washing machines, radio, planes, electricity, cars, metros & trains, engines, cameras, back to writing & even making fire- developing nouns, verbs, constructing languages. online booking is 1 nice example of how life can change n a relatively short period. again nice post- well done & have a great day
