Hahaha! Over my simpleton brain.
Displaying "Hello World" on a computer screen is one of the first things programmers do when learning to write code (in any language). I probably first did it in Cobol and Fortran and Pascal and Lisp and Assembly and Basic and C and who knows which language about 99 yrs ago, output on tractor-feed paper on a mainframe computer.

I do a lot of coding on microprocessors now, and often when writing drivers for communications, I start with a repeated "Hello World" spewing out of the comm channel, then monitor the output to see if the driver is working correctly. I'm a lot closer to retirement than beginner, but it's still a goto phrase for me. (I'm not a programmer, mostly electronics hardware design, but almost all of that hardware design requires processors that need code).
