Muddiest Point for 9-27 - 10-1

My muddiest point for this week is more of a question than a misunderstanding.  Since technology is always advancing, I wonder if the various formats (GIF, JPEG, TIFF, and PNG) will always be available in the future? If not, will they be able to be converted to newer forms so that the information stored in these files can be accessible to users in the future?
