Why would anyone choose Docker over fat binaries?

Just a sidenote, a part of this article reminded me of the RFC2110 - The naming of hosts, an old april fools RFC.<p><a href="https:&#x2F;&#x2F;tools.ietf.org&#x2F;html&#x2F;rfc2100" rel="nofollow">https:&#x2F;&#x2F;tools.ietf.org&#x2F;html&#x2F;rfc2100</a>

I wondered this myself 2 years ago and went with fat binaries (uber jars, actually.) Unfortunately fat binaries aren&#x27;t an option for many languages...
