By 2035, I think physical passports might still be needed, but we’ll probably see a lot more digital integration for convenience. Biometric data and digital passports could make traveling easier, but some countries may stick with traditional documents for security reasons. I love traveling and enjoy exploring how tech evolves to make it smoother. It would be amazing if everything, from boarding passes to visas, could be handled digitally! Recently, I was booking event tickets and needed the SeatGeek phone number, which reminded me how digital solutions have streamlined so much already.

Betting against both the strong (majority of countries by number of countries) and weak (countries making up 51%+ of the world’s population, say) interpretations of “most countries”, though I could see trouble with something like “China and India issue and honor each other’s digital passports”.

Presumably this will be easy to resolve negatively, but I’d be curious about how to evaluate separate digital passport networks / reference countries.
