Besides you or I, lots of things. Knowing what will not be around could help you plan on making more wise buying decisions. Life is evolving quickly. Just like rotary phones and pony express are a romantic memory now – so will a lot of gadgets we use today. The change is already afoot. It also is a good way to know what not to spend money on, for surely sooner or later these ‘things’ will not be part of our life and will have to be carted to the “unwanted things grave” by you or someone else. Likely someone else if you are like most people and want to hang on to things that you paid good money for.
Look at this list of items that will soon be gone by AARP, good stuff to think about: http://www.aarp.org/entertainment/style-trends/info-06-2012/world-without-toilet-paper.2.html
