This is just yet another example of a pointless argument, exactly as I mentioned. Why should I even care that you can scavenge for ancient stock (even if NOS), when my current concern is about something that is still manufactured _today_ ?

I know for sure optical media & DRIVES will still be available to purchase _brand new_ during the N years they're still manufactured, but also the M years that will follow where I will be able to find new/old stock after they stop manufacturing.

Period N by itself I expect is going to be somewhat long (see 3.5inch floppies), during which one can even expect to see drives with never interfaces (e.g. USB-C). Yes, I have no clue how long it is really going to be, and my concern is whether it will even last this decade.

OTOH I know 100% for sure period N is going to be effectively 0 for any LTO generation I could possibly buy. By the time LTO prices drop for some generation, it is because that generation is dead in the water.

And period M? It is going to incredibly long for optical due to popularity alone, much longer than _any generation_ of LTO could ever hope to be.

And if you say "well, certainly some form of LTO is going to be manufactured in 20 years from now": it should be obvious that I couldn't care less, unless that form of LTO would be able to read the tapes from any generation I can possibly buy now.

The fact that LTO-21 will still be manufactured is of absolutely no relief to someone with LTO-4 tapes. In fact, for all I'm concerned, it could very well be an entirely different media type only sharing the first three letters of the name.

These are not arguments in favor of LTO. If you're already assuming that if your LTO drive breaks you either scavenge for another or basically assume the loss and buy all new media from newer generation and repeat... what's the point of LTO then? Why not buy SmartMedia cards (to say the worst thing that comes to mind)? I'm sure you can scavenge readers and media, and probably will have an easier time finding and using them than with any specific LTO generation.

In the meanwhile, let me keep burning toasters; at least there is a small chance I may be able to buy new drives 20 years from now, using whatever interface replaces USB-C, and they will still be able to read my current discs.
