Right? Here in the Netherlands, Teletext is still very much alive and has several millions of users per week. [1]
In fact, at the end of 2023 our public broadcaster rewrote the Teletext backend system using modern programming practices to keep it running into the future. [2] Before that it was running on software from the 80's.

That's VoiceOver on iOS. It's a screen reader that's also available on the Mac, iPad, and Apple Watch. Android has a similar screenreader called TalkBack.
I work with visually impaired people on accessible apps, and the large majority of them prefer Apple's devices because they have more advanced accessibility features.
I don't know about Philae/Rosetta's hardware in particular, but there are very specific requirements to hardware that's sent into space.
I'm using the Mars Science Laboratory as an example here:
The MSL uses twin PowerPC RAD750 boards. If one of them fails, the rover could use the other as a backup. After all, you can't go out to Mars to fix a firmware update gone wrong. :)
The RAD750's are hardened against radiation in space, and can withstand extreme temperatures. They run at about 200Mhz, and cost around $200.000 a piece. [1] [2]
It runs the realtime operating system VxWorks, which also happens to be what Apple uses for their Airport routers. :) [3]
NASA uses C as their main language, with specific coding standards. [4]
