TVs, thermostats, "smart" anything, android phones, 3D printers, industrial equipment, routers, sensors (e.g. soil monitoring where there's millions), and zillions more categories.
Remember: Just about every "smart" device that's connected to the Internet is running Linux and isn't getting compromised anywhere near as often as embedded windows devices did (which is a big reason why companies stopped using embedded windows!). There's vulnerabilities that crop up from time to time (e.g. cheap routers) but that problem can often be attributed to shitty practices on the part of the device manufacturer. Example: Using the same default credentials on every device, expecting the end user to change them.
In short: The anime left a scientist bamboozled.
