To be fair there was no one tracking the migrant boat because they were crossing illegally. We knew the sub went missing basically as soon as it did rather than when people started spotting bodies. In situations where migrant boats are found before/in the midst of sinking help is sent (although after that it’s probably a trip to the detention centre.)
I haven’t heard it called this before but I agree with others that the general concept is a good idea. We are far too quick to jump to the next processor, the next monitor etc. when those things can realistically last a very long time before hitting too much of a performance limitation (especially for people who don’t render anything like high games or video editing.)
