Sure; after Casey Muratori saying that people argue with him that no normal developer needs to worry about performance, computers are fast enough, performance is a niche concern, I'm just musing how little data it takes - 64k is nothing to a modern person - and how abruptly anyone who wants a fast answer has to switch to think about performance, pre-processing the list, sorting more promising candidates first, using a faster language, noticing that it's embarrassingly parallel, etc.
