Even when there comes a point when CF cards are no longer manufactured, I'm sure you will be able to order old stock for many years to come. Not long ago I needed an electron tube that had been out of production since 1957; after a brief internet search I soon found a supplier in Canada who had several tubes of that specific model in warehouse. A few days later, the desired electron tube arrived at my door.
It would be interesting to see what digital cameras would look like if the transistor had not been invented and they had to use vacuum tubes! They would probably come with a ball hitch and wheels for easy portability!
