Here's a thought experiment: think about last month. A meal that surprised you. A film that stuck with you. A hike where the light was just right. A conversation worth keeping.
How much of that do you still have?
Not in a vague sense — specifically. The restaurant's name. The movie's title. The trail you walked. The thing that was said.
Most of it is already gone. Not because it didn't matter, but because nothing was there to catch it.
Every AI assistant you've ever used had one thing in common: it knew nothing about you.
It didn't know you've been training for a half-marathon since January. It didn't know your mood tanks every time you skip more than two workouts in a row. It didn't know you loved the last thriller you rated 5 stars, or that you've visited 12 national parks and always head back to the mountains.
So the advice it gave was generic. The suggestions it made were guesses. And after the conversation ended, it forgot everything.
Guide is different.
