Isn't primer usually better on dry spots, not just oily zones? I mean, putting it all over might work if your whole face gets shiny.

Exactly, tech can't replace experience.

The automated manure spreader that failed at the Olsen farm last spring ruined 40 acres of alfalfa. It wasn't just a stink, it was a total loss of that cutting. Old methods might be slower, but a broken tractor doesn't poison your land. When new tech fails that hard, the cost isn't just a cleanup, it's someone's entire income for the season. Sometimes the old way is the reliable way.

Ever heard of a solar charger doing something similar? My friend had a portable one that would supposedly adjust its output based on sunlight, but it kept beeping randomly when clouds passed. We thought it was malfunctioning until we realized it was trying to 'optimize' itself in real-time, which led to a comedy of errors during a picnic. People were scrambling to find the source of the beeps while it was just the charger having a moment. It became this inside joke about technology being too smart for its own good, and we still laugh about it years later.
