The biggest problem with modern tech for me is that it almost never works as advertised. A lot of times it's just there to tick a box on the marketing material. The most recent example, got myself a new Fuji camera and it has bluetooth and wireless and a smartphone app and theoretically you can transfer your pictures wirelessly (but not over a physical usb cable). I'd rather it didn't have these features, because it's not reliable, sometimes it won't work at all, other times it takes too long to connect, it's a mess and I have no time in my life to deal with this crap anymore.
I totally agree. For file transfer on my Fuji camera, I just take out the SD card and grab the files on a SD card reader (+ usb-c adapter) on my phone.
(The Fuji wireless app won't let me transfer regular JPEGs or RAW files. Only compressed JPEGS less than 1MB large even though the original JPEGs are ~2.5 MB big.)
The biggest problem with tech is that the "smartphone app" is basically immediately on a (usually steep) decay curve of support.
Usually with no basic protocol backup, such as a basic web api, cli, or filesystem interface.
Of course that's a feature for hardware manufacturers. No one wants a device used for decades, even though that's exactly the level of support necessary to make IoT successful in consumerland.
That apple intentionally breaks things that aren't broken / forces upgrades within its walled garden is even more despicable
