These should be USB sticks, but otherwise this is preferable to something like wifi.
You do not want to stop requiring physical access to avionics for updates and reprogramming.
The fewer surfaces for entry into the avionics systems the better and if that means an engineer schlepping a database update on a thumb drive to the cockpit that's what you want.
I spent the better part of a decade on avionics, and while this as a headline sounds bad it's one of the few things Boeing shouldn't be mocked for right now.
Boeing could supply virtual floppy drives that take USB drives or SD cards if they wanted to. I'm sure they don't want to spend the money getting one certified until they are forced to though.
Floppy disks will continue working fine until the supply of new old stock disks runs out or becomes unreliable.
Certification is expensive. But updated dbs are pretty huge and seem to only get bigger over time. Stuff like radio firmware tends to be in the hundreds of KBs though, so for that it really wouldn't be a big deal either way.
I don't think the article argues against physical access though.
It doesn't, that's just a very common reaction to these types of articles. I recall having some very intense discussions around stuff like iPads in cockpits. I'm on the "not a fan" side, but I'm also not making avionics software anymore either.
iPads used as an electronic flight bag beats having a huge stack of papers to shuffle through. There’s only one disaster I’m aware of caused by an iPad, and that’s on a military Chinook. It got wedged below the pedals because they didn’t stow it as they should have.

It's not the iPads themselves, it's the addition of Bluetooth and/or wifi to support them. I agree that they can alleviate a lot in terms of paperwork reduction etc. My issue is the additional exposed surface.
Wireless isn’t a requirement and connectivity seems slow to be adopted anyhow according to this source.
