Unfortunately, quite a few security practices are sometimes "impractical". If you go purely by practicality, all computers would always trust you and do as you request — what is that if not the most practical way of interacting with a computer?
You always need to decide where to place your personal trade-off, maximize in that direction, and be honest about it to yourself. If you don't care about security to this degree, buy an iPhone. If you don't care about their known shortcomings, use face ID and/or fingerprint sensors. Or buy a different phone.
> way devices are going. Look at iPhones.
Also, FTR, almost all US people have a distorted view of iPhone market share. It's only the US where they have about half the market. It's far less in the rest of the world. That said, they still have somewhat of a "technology leader" position where everyone else feels like they have to imitate it, so… meh.
