This is a rather poorly researched rehash of the same claims and arguments making the rounds on on the interweb over the last year, with very little if anything new to say... nor does this article make any coherent point that ties back to the title.

Consider the title: ancient computers on the 737. Does the article explain why the computers are ancient? Does the article explore, at any depth, the world of safety critical avionics engineering? Does the article discuss how Boeing and regulators are working to solve the problem, with new or useful information to share that hasn’t been shared before? No, no, and no.

For those interested in the world of avionics software and why old CPUs are prevalent in modern aircraft, I suggest googling DO-178C, DO-254, and the to-date necessity of single-order-execution environments for safety critical flight systems.
