I think you aren’t asking the right questions. You, me or the people who were in that class aren’t the ones that will be inventing or pushing for the adoption of whatever new technology or trend might make us seem outdated 30-40 years from now.

The inventors of those haven’t been born. They will be impacted and grow up with stuff that will be popular 10 or 15 years from now.

All the examples you gave are pretty easy to go: “yeah marry and android; sure eat a mealpill; do the isntamatch, if it works it works”. Because they are what you can think about. Someone who lives today, and has grown up with all the tech and things we already know.
