That&#x27;s definitely a valid objection and I have absolutely no idea what could be done about that. But as it is the bug that takes down one machine today will take down other machines tomorrow and yet other ones five years from now.<p>So for entirely new bugs your objection stands, they could (and likely would) be disastrous. Even today a &#x27;zero day&#x27; exploit for a major platform can be dealt with though, I don&#x27;t see why we would not be able to deal with such exploits in a scenario where there is only one implementation of something, it&#x27;s not as if right now we use the other implementations to keep things running, it&#x27;s mostly a matter of impact all at once rather than spread out over time and infinitely repeating.
