LP reliability?

[CTRLSHFT]

I dunno why but I get the feeling that in 20 years rubber buttons will begin to rot or harden and lose elasticity like old rubber usually does... am I alone on this? 20 years down the line it may be unusable... and I cant see how there will be replacement switchmats... its not like a knob or switch... It's an elaborate thing to have manufactured...

consider though that the rubber produced these days probably uses different hybrid polymer combinations.. you definitely have a point, but i wouldn't be suprised if the stuff made now is way more durable.
