It&#x27;s worth expanding that this is a very broad spectrum of software.<p>No one&#x27;s worried about assembly code for Intel chips, but the next generation could be locked down.<p>No one&#x27;s worried about writing C++ for Windows, but technically you&#x27;re using their APIs and hooks that could be dropped in the next release.<p>There&#x27;s iOS, where you&#x27;re also subject to review and approval.<p>There&#x27;s well-known web joints like Google, where this can happen.<p>Then there&#x27;s the fly-by-night shops that could just dissolve tomorrow.<p>The <i>safest</i> thing is to build your own computer from silicon, write your own OS, your own compilers, your own languages, your own software, and your own APIs. Of course, by the time you do that, we&#x27;ll all be dead. So it&#x27;s a balancing act. But it&#x27;s worth illustrating that you&#x27;re taking for granted that things will remain the same forever, when in reality there&#x27;s a sliding scale of risk.
