Literally the opposite is happening. Look at any busy store: self checkout can handle like 10 people, compared to registers which are significantly less at any given time. Registers account for much less business, and corporations are going to try and get by the minimal amount of employees as possible to function. Handling physical cash also adds more complexity with tills having to be deposited, audited, and withdrawn daily.
I'd just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
Been using Firefox Android for quite some time already. It's been my perfect browser pretty much. I'm glad more extensions are coming, so others can enjoy it as well, but I'm happy with just Dark Reader + uBlock Origin lol.
No lol
