Repairability and no more serial number locking for replacement parts.

To the best of my knowledge all non-volatile flash memory goes bad eventually. It cannot be prevented and can happen without warning. I suggest marking them with the date they were first used and just get rid of the old ones after a year or two if you use them heavily. It’s a bit of a waste to throw out stuff before you know it’s gone bad but it’s pretty minor if this is how you make a living.

Also, a camera with multiple SD card slots can help. If you don’t have one of those, buy multiple SD cards and just swap them out during the day. If one fails, you only loose so much.

I don’t think this is a “these kids these days” issue. I suspect this sort of thing has always been around.

It’s just that these days the internet facilitates communication and allows for a post to reach more people and more people to reach back out. In the past they would have had to go up to you physically to talk, now they can fire off hundreds of dumb questions form the comfort of their bed.
