Could be Fadell, why else would Apple put Thread in phones? Maybe iTunes Store (via Fuse) and iPhone (via General Magic) weren't the only things Fadell had pitched Jobs on when the time was right.
I tried the cheap IKEA model and with my severe dust mite allergies the model was insufficient in comparison to calm my sixth sinus-bound sense.
My main suspicion: In my last 3 abodes with pre-1955 construction in East Coast, the pre-filter on the top Wirecutter pick needs to be cleaned 3x per carbon filter replacement in order to reduce largest particle accumulation on the carbon or HEPA filters.
The inexpensive IKEA model did not have a viable and easily cleaned pre filter as far as I could figure out.
The ikea Fornuftig has a snap-on piece of cloth covered plastic that serves as a pre-filter, a replaceable particle filter, and a replaceable optional gas filter.
I've found that taking a shop vac and leaf blower to the pre-filter works quite well to get it clean.
That said, the Ikea air purifiers only make sense if you have a room that's about the right size for the Fornuftig. Their larger purifier is worse value, and you're better off looking at something like the Squair.
Fun fact: That long s accidentally lead to a new character being created.
In German, we've got words like "dass". Back in the day, every s that wasn't at the end of a word was written as long s, so "dass" would've been written like "daſs", which got turned into ß.
That's why until the recent orthographic reforms of 1996 and 2006 "dass" was written as "daß".
Aside: in some regions, "dass" would've been written like "dasz" / "daſz". That's why the letter is called Eszett (S-Z) even though it's capitalised as two consecutive "s".
To make the language easier to learn. Lots of languages go through orthographic reforms from time to time, English being one of the notable exceptions because there is no central authority that could impose rule changes in a way that would ensure that most language users eventually fall in line.
I entered school in Germany the very same year that the orthographic reform came into force, so I never learned the legacy spelling, but I certainly found it weird how much adult people at the time detested the rules that six-year-old me considered to be very reasonable (esp. the ss/ß reordering and the ban on fusing tripled consonants in compound words).
I know some conservative newspapers (Frankfurter Allgemeine Zeitung) kept using the old orthography for a while, but even they started using the new one in 2007, ten years after the reforms.
Illich's 1983 Japan talk seems to be in response to McLuhan's 1971 convocation talk where he critiques Illich: https://mcluhan-studies.artsci.utoronto.ca/v1_iss5/1_5art3.h...
(The spacing on this document I'm linking is hideous. Excerpts inlined below, paragraph breaks my own)
Both talks center "enterprise" and communication. Thanks Claude for validating my hunch about the late-century subtweet.
> What has happened today is that there is a new hidden ground of all human enterprises, namely a world environment of electric information, and against this new environment the old ground of 19th century hardware—whether at school or factory, whether of bureaucracy or entertainment—stands out as incongruous.
...
> It is this situation that Ivan Illich addresses himself to in Deschooling Society. He is vividly aware of the irrelevance of current curricula, drills and certification. He knows that these can no longer help us relate to the new world, and he frankly appeals to the forms of preliterate, and even prenatal experience as models for the training now needed.
> As Coleridge said "If you wish to acquire a man's knowledge, first start with his ignorance." Illich is unaware—I'll repeat: Illich is ignorant of the new all-inclusive "surround" of electric information which has enveloped man, but it is his instinctive response to this new ground that in some measure validates the figure-image he suggests for the new school. For example, he says "Since most people today live outside industrial societies. Most people today do not experience childhood. In the Andes, you till the soil once you become useful: before that you watch sheep; if you are well nourished you should be useful by 11, and otherwise by 12."
> Illich relates this story: "Recently I was talking to my night-watchman, Marcos, about his 11 year old son who works in a barbershop. I noted in Spanish that his son was still a nino. Marcos answered with a guileless smile, 'Don Ivan, I guess you are right.' I felt guilty for having drawn the curtain of childhood between two sensible persons." What Illich has in mind, although he does not state it, is that childhood was unknown in the Middle Ages and was a renaissance invention that came in with printing, and is ending very rapidly now in the television age...
