What would you build? If you could compile to Win+Lin+Mac

Hello Smart Babiato friends, just wanted to share something I am excited to learn today,
and also see if anyone else is looking into this.

TL;DR
Someone (https://justine.lol/) figured out a way to create a single binary executable that will
run on our common hardware platforms and (windows, linux, apple). Appears to be x86 and ARM(not sure).
Works like a web server with a .zip package payload containing your script and media.

You can download it here - free

Questions:
1. How much of a game changer is this?
Good bye cross compilers, good bye multiple OS devs.
Not really - but possible if you app runs in the web browser.

2. What would be a good project that could really benefit from this?
Note it only has console I/O no gui, so I am thinking backend for serving
tcp/webpage. In my mind this is like electron that VScode is written in
but now you target multiple platforms and develop in platform you like

Thanks cKeeper., I agree with your sentiment. Big and small corporations have a lot to lose if this catches on.

The only way it can be patched by the OS is by looking at the executable header and prevent the executable from loading into memory. I forsee a few novel applications coming about.

Looks like an ARM emulator may be available making it easier to write iPhone, Android and x86 apps. in one executable.
