I don't trust any of my devices anymore (including/especially my car). At the very least I figure that they're spying on me. In the most extreme cases, such as Israel's terrorist pager attack, they may even kill you.
I wonder if this is going to create a market for older tech/vehicles that were made prior to ease-of-malware integration? I imagine some sort of cyberpunk future where people are scouring landfills for old 16-bit video game console chips that haven't been backdoored.
