Self destruct?
More than that.
I had a K200D series turn on me. Became disobedient to my instructions and ultimately zapped the family pet with a red-eye flash ray.
I felt I was in the middle of "I, Robot", the concepts of Isaac Asimov running through my head as I sought safety from the electronic devil on the second floor attic.
After hearing things break and shrieks of pain from family members at what they saw, it all became silent.
I huddled amid tepid clothing, clutching my *ist D series camera.
When the attic door opened I was blinded by the light, all I know is that the *ist D came out victorious. And I am here to write these words.
(Just in case I was kidding)
Hey all electronics fail. My thinking is that they will fail much faster than any mechanical film camera ever will.
My suggestion is go out and shoot as much as you can, while you can, with your DSLR. No better time than now.
