Not all plastics are made equal. Two different 1.5 or 1.6 index plastics from different manufacturers will have different scratch resistance as well as different levels of aberration depending on how good their materials science is.
All plastic is softer than glass, yes, which is why any plastic lens you get has a hardcoat to reduce scratching and if it is from a quality lab, a scratch/antireflective coat as well.
If you’ve never had plastic lenses last very long, where you are sourcing them from is using inferior quality plastics with whichever lab partner they use. That or you a) leave them in a hot car and the heat damages them b) constantly leave them lens-face down on the table
But I have had people with very stable prescriptions keep plastic lenses in good condition for 15-20 years in extreme cases.
Laminated glass treatments may be used, but because they cause problems with the cutting machinery it is far more common in optical glass lenses to see chemical or heat treating. If these are done well, they can be quite resistant to shattering. This, however, really comes down to the individual skill of the person treating your lens and I’ve seen enough damaged eyes to be wary of them.
Another reason many labs have moved away from mineral lenses entirely is that they shatter when being cut to shape for your glasses, posing greater risk to the one doing the edging and significantly greater cost to the lab. Depending on the complexity of prescription they may shatter up to 3 or 4 times before one cuts properly into shape.
To add onto this, if you are using progressive glasses, you are certainly getting an inferior product as no lab I’m familiar with puts their new progressive designs into mineral. The majority only have designs from 15-20 years ago with terrible intermediate segments.

My favourite “obscure” artist right now is a Vancouver band called Slightest Clue. Post/Punk alternative group.
Quality plastic lenses can last that long. Often being able to keep glasses that long depends most on the stability of your prescription, and not going for bottom of the barrel coatings.
Glass lenses are harder to scratch, but are heavier for the same prescription and if you get hit in the face can shatter into shards that are quite damaging to the eyes.
If getting hit in the face is not a risk for you and you dont mind the extra weight go for it, but it’s worth noting there are some downsides as well.
Fun fact, many of the intra-ocular lenses and contact lenses that provide UV protection do so just by the properties of the material they are made of, not any special coating.

Yeah, AZW3 was the format I was thinking of. For things purchased from the amazon store for the kindle they will be in that format. If you want to move your amazon books library elsewhere you have to use some funky plugins for calibre to convert them to a standard format like mobi or epub

My understanding is they arent mobi files anymore but a proprietary DRM format. That being said, there are many wonderful calibre plugins that break the drm.

While I agree with you, any politician with an R beside their name is going to actively obstruct everything you just listed.
So then it becomes what takes more political capital, one thing they’ll fight tooth and nail or ten?
I’ve found openSUSE tumbleweed to be the perfect mix between stable and constant updates. By default uses brtfs so if you break something the fix is a simple as rolling back to the snapshot that was automatically made right before the update
