Absolutely not... but hear me out. NetBSD plans on supporting 32-bit x86 until "long after 2038 (http://www.netbsd.org/about/)." Legacy hardware matters for many reasons. Outside of the fact that I still love my Lenovo x60s and use it as a distraction-free writing machine, much of the world still depends upon 32-bit architecture. We can't be replacing computers for all 8 billion people on Earth every 10-20 years. Hell, think about all the government bureaucrats still running MS DOS! :-)
