Solved but now unsolved problems in computer science:
- copying files off a phone without using a network/cloud/internet

Tech bros be like:
- we built 16k 120fps camera into your phone
- beam forming wireless
- advanced ai multi core gigacore 2TB 3d array ram

The end user:
why does it still take 3 hours to copy vidoes off my phone

@xssfox the only reliable methods to transfer files off Android that I've ever found are:
- run an ssh server on the phone and scp or
- get the developer kit and adb pull over usb

It's kinda... Amazing.

@elladan @xssfox
you can use ADB on Linux without a developer kit.

Not very user friendly, so I use Total Commander and the SMB plugin on WiFi. SMB is like Windows share, so available on Linux. Windows Share works with Total Commander and the SMB plugin too. About 100x faster than USB!
Crazy.
Google doesn't allow Android apps with full file manager unless they are only a file manager!
Also they keep changing how SD card access works.
