A lot has happened in CSS in the last few years, but there’s nothing we needed less than the upcoming Olfactive API. Now, I know what you’re going to say, expanding the web in a more immersive way is a good thing, and in general I’d agree, but there’s no generalized hardware support for this yet and, in my opinion, it’s too much, too early. First let’s look at the hardware. Disney World and other theme parks have done some niche so-called 4D movies (which is nonsense since there isn’t a fourth dimensional aspect, and if you consider time the fourth dimension then every movie is fourth dimensional). And a few startups have tried to bring olfactory senses into the modern day, but as of this writing, the hardware isn’t consumer-ready yet. That said, it’s in active development and one startup assured me the technology would be available within the year. (And startups never, ever lie about when their products will launch, right?) Even if it does come out within the year, would we even want this?…
