You and er, Madison, right? This article is riddled with generalisations, oversimplifications and many comments that are vague to the point of being almost misleading - or certainly of limited value given the lack of context. This is the level of technical article I increasingly encounter out there these days... In a way I suppose it's good in that we all have to fall back on reputable sources again rather than be tempted to hit a search engine where we will this sort of traffic-generating, borderline chatgpt, cut'n'paste salad, complete with occasional chirpy "WAL is a gamechanger!" sorts of comments. And a 'deep-dive'? Sheesh. Anyone looking for a reasonably deep dive - and the first encouraging sign you might notice is that it's >1500 words - could do a lot worse than go here...
