One plus of electric cars is the motors will retain their same performance over their lifetime. If they don't have infant failures they'll have consistent performance for 500k miles or more, with no degradation. Might need to replace the bearings along the way (and hopefully they make them bearings serviceable).

Definitely true. But much like we saw on hybrids, (and not the 4th gear missing type), the motor is seldom the issue. Even things like the inverter are simple and robust enough they'll last long enough, and be cheap enough to replace. What's going to put a vehicle out of service is the battery and main computer. With the battery performance will degrade over time. Unless the reman process gets way more widespread and efficient, a battery replacement will probably determine when a car gets disposed of- when the replacement exceeds the value, it's gone. If we're lucky, maybe down the road companies will standardize on cells, but for now, proprietary designs are too profitable for them. Then the follow up is the computer. The cars are becoming increasingly reliant on a single computer for the entire vehicle, both powertrain and chassis. That means you're more at the mercy of something more akin to regular consumer electronics than the lower tech but more robust ECUs of today. When that's no longer supported, you're on thin ice (no pun.) I doubt that companies will spend the extra money to separate it into two modules, especially with the current chip crisis in mind. Though eventually I would anticipate new EV standalone systems to pop up.
But still, it makes it much more like a consumer electronic in the end. It's like an iPhone. Most of the hardware will last, but when the battery is toast and the software is no longer supported, it's trash. And if you've seen the new Volvo EV commercial, it's marketed just like a new phone. All about software/features, UI looks like a phone, and even showing off the colors like a phone. Nothing about how they drive/feel. They're electrical appliances. No more, no less.
