I have two reactions: 1. The headline is rather silly. 2. There's no way this little script, although it might conceivably be useful to someone, needs to be a youtube video.
Isn't the whole point of assembly that there is no compiler?
Right, they just use an assembler and a linker ...
I mean they're not wrong...
This is why my next book will be titled "how to cook dinner without a compiler, GCC 4 to GCC 11 compatible!"
I was going to click on this until I saw it was a video.
I need this on a t-shirt
Putting aside the misleading title...
Because this writes to and then runs an executable file with a known name, this script should never be used on a multiuser system in a directory where another user has write permissions. It is vulnerable to a timing attack where the attacker copies an executable they want run with your permissions between this script creating the file and running it.
I'm still super confused by this user's posts lol. I get that (some? most?) of it is satire... but then why all social media engagement farming hashtag nonsense? Or is this all part of the satire...?
Here is an alternative Piped link(s):

Piped is a privacy-respecting open-source alternative frontend to YouTube.
I'm open-source; check me out at GitHub.
Perhaps we should reconsider the definition of write-only scripts.
