Huh? Cashback cards on VISA/Mastercard have all but disappeared, I think Lloyds still do one but it has a promo of 1% for the first year then drops to 0.25% after. American Express will give you 0.75% on first 10k spend then 1.25%. 2% is unheard of (unless it's promo or heavily capped).
It's not just the WebKit bit, basically the entire app implementation is actually shipped as a "Private Framework" which lives outside the .app bundle. e.g. on macOS
% otool -L /Applications/Safari.app/Contents/MacOS/Safari
/Applications/Safari.app/Contents/MacOS/Safari:
/System/Library/PrivateFrameworks/Safari.framework/Versions/A/Safari (compatibility version 528.0.0, current version 623.1.14)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1356.0.0)
There's a bunch of other private frameworks (SafariCore.framework, SafariFoundation.framework, SafariPlatformSupport.framework, SafariShared.framework, SafariSharedUI.framework, SafariSwift.framework) as well. I haven't checked but I assume it's similar on iOS.
Barely supported by Apple these days - in addition to needing to disable SIP which is a pain, it was broken causing system freezes for several major macOS releases.
QuickTime for Windows existed long before then, and Apple ported a bunch of the old Classic Mac Toolbox to Windows as part of that.
IIRC it was actually this Windows port of Toolbox that in some ways laid the foundation for Carbon - i.e. a port of the Toolbox API to what became Mac OS X.
I wouldn’t hold not being on the Mac App Store against it. The MAS is sort of a failed ecosystem with very low usage/engagement, and all the downsides of the iOS store like potentially lengthy review times (can be a lot longer than the iOS store since it seems to play second fiddle) and arbitrary capricious rejections when you’re just trying to ship innocuous bug fixes to users.
Doesn't help you if the pilot flying is incapacitated by the toxic air in less than a minute, or crash in to mountains, as in the scenario posited in the video. Climbing out to an appropriate height to join the approach, reconfiguring the plane for landing etc, takes several minutes; an immediate forced 180 teardrop back to land is very challenging to execute successfully (see the tragedy at Jeju just before new year).
A significant portion of human structures are located close to the coast (seaborne trade having been a huge enabler of economic development for a few hundred years) and are exposed to flooding from rising sea levels, or built in valleys that are increasingly at risk from flooding due to far-above-long-term-historic-norms precipitation runoff (higher atmospheric temps lead to more energy in weather systems; see eg massive floods in Europe in the past few years).
That is certainly true of Flutter, which has its own rendering pipeline. React native, if you create a Button then on iOS you'll get an actual UIButton instance constructed, etc.
