Many of them will have been customised by phone manufacturers and/or network providers, rather than using stock Google versions, so a Google provided update wouldn't necessarily apply.

Let's Encrypt warns about a third of Android devices will from next year stumble over sites that use its certs
Did I or did I not ask you to double-check that the socket was on? Now I've driven 15 miles, what have we found?
Re: Imagine anything as efficient
Apollo's first workstation worked around the 68000 limitation by running two processors, with the second one slightly behind the first, and swapping between them on a page fault - the second one didn't have to recover its state, because the MMU had already done its work when the first one hit the fault.
Re: Old news
This doesn't just work if you've turned off the GPS, it works with saved data if you don't have cell connections to triangulate, for example in airplane mode.
(Only if you later make a connection that the app can send data on, or your phone is seized, but if you never make a connection, why have a phone at all?)

Sort of wrist mounted equivalent of https://www.smarthalo.bike/ ? That might work. Not that I'm totally convinced by the SmartHalo, even though riding a bike obviously is a case where "why not just take your phone out of your pocket and look at it" isn't that convenient.
(Another is swimming. Not for maps/navigation, but with my glasses off I can't read a clock on a pool wall. I haven't actually tested the swim lap counter app on my Pebble original (£50, charge once a week) yet, but it was one reason for buying it.)
Re: rm -rf /etc /bin /usr
See also the classic tale from 1986 at http://www.ee.ryerson.ca/~elf/hack/recovery.html
"Meanwhile James had made for our tape cupboard and had retrieved what claimed to be a dump tape of the root filesystem, taken four weeks earlier. The pressing question was, "How do we recover the contents of the tape?". Not only had we lost /etc/restore, but all of the device entries for the tape deck had vanished."
"Alternatively, we could get the boot tape out and rebuild the root filesystem, but neither James nor Neil had done that before, and we weren't sure that the first thing to happen would be that the whole disk would be re-formatted, losing all our user files. (We take dumps of the user files every Thursday; by Murphy's Law this had to happen on a Wednesday)."
While HTTP/2 does exist, as others have already said, this is about version 2.0 of an _implementation_ of a protocol, not versions of the protocol itself.
OpenSSL hasn't had a 2.0 release (1.1.0 is in beta), but has had many releases over the last seven years, and is very widely used. Netscape Security Services is now at 3.21, but that doesn't mean it's three times as widely used as OpenSSL. Mostly this just shows that different open source projects use different release numbering schemes, and can't be directly compared.
(The same is true of protocol versioning. That SSL had versions 2.0 and 3.0 and TLS is working on 1.3, doesn't mean TLS isn't used as much as SSL was, it means that TLS designers had learnt from SSL mistakes, and haven't had to introduce a totally incompatible version.)
Re: Other reasons it has not been dropped
Still draft - https://datatracker.ietf.org/doc/draft-irtf-cfrg-chacha20-poly1305/
Not yet supported by Mozilla, in part because of that - https://bugzilla.mozilla.org/show_bug.cgi?id=917571#c19
It's got a very long way to go before being as common as RC4.
> Why would malware need to communicate with another machine, which would already have that malware installed, especially if over such a short distance?
Send new updates, and/or repair malware which has been half removed.
And send _back_ sensitive information which was carefully being kept on an air-gapped computer, but put on it in the first place using USB sticks, one of which turned out to have been infected.
That degree of low-level cross platform USB driver bug compatibility seems far fetched though.
> partially blocking the exhaust nozzle of the rocket motor?
When he says "without a burst plug or other means to retain internal pressure", presumably a burst plug is something that will block the nozzle during ignition but reliably rupture in a consistent manner once pressure has built up.
How hard would it be to add one to the design?
Farmer's Riverworld had a balloon with heated gas for extra lift, based on Verne's story. (The aliens had carefully designed some barrier mountains to be just impassable with conventional hydrogen or hot air balloons using the available technology, but hadn't thought of using hot hydrogen. (Helium wasn't available in the setting.))
And there was (I think) a AC Clarke story featuring hot hydrogen balloons heated by naked flames - perfectly safe, since the burners used tanks of pressurised oxygen as "fuel" to burn in a hydrogen atmosphere, where neither unheated hydrogen nor helium would give any lift at all.
