The Half-life of Software

We usually design software with an implicit assumption that it will live forever. Or, maybe, 10 or more years which is kind of synonym of "forever" in IT. I'm challenging this assumption with numbers I collected while analyzed 200+ discontinued software. The hard truth is that 50% of software products you write today will disappear from the market in the next 4 years. Details you find in my new article The Half-life of Software.
