Not least because there’s no such thing as a “compiled” or “interpreted” language.
I’d say there is (but the line is a bit blurry). IMHO the main distinction is the presence (and prevalence) of eval semantics in the language; if it is present, then any “compiler” would have to embed itself into the generated code, thus de-facto turning it into a bundled interpreter.
That said, the argument that interpreted languages are somehow not programming languages is stupid.
a mobile OS that basically eschews backwards compatibility
I have an app built for Android 4 running on my Android 15 device. It looks ugly but it works. Of course other apps will not be so lucky, but some backwards compat is absolutely there.
a desktop OS that can still run 30 year old applications
Not really, Microsoft is steadily breaking old stuff. For example lot of 10-15 year old software that was doing something hardware-related would be broken now due to driver signing changes/restrictions (e.g. WinRing0 things).
the most popular OS
It’s barely the second most popular OS, after Android. iOS is pretty close behind it. And yet the amount of complaints Windows gets seems to be far higher than that of Android.
Not an exact alternative (it’s missing reviews and photos are relatively rare), but I use OsmAnd for this. Most “official” trails (e.g. those maintained by the park administration, etc) are mapped on OpenStreetMap already. There’s also support for “Travel Routes” (I think they come from WikiTravel? Not sure); this covers the most popular “unofficial” routes. Once I ran out of those, I started just looking at mountains without trees but with a path to the summit marked on the map. This way, I’ve been able to find hikes for almost every weekend for three years now (definitely over 100 at this point) in a tiny country (Georgia); I’ve obviously had some misses (paths being overgrown, trails being meh, etc) but overall I’ve found it really nice.
