Messaging apps are a lot harder to get right than you might think. I worked for years on messaging using XMPP and the problems were legion. I'd be very interested in seeing how a vibecoded app does at scale, especially with the presence problem.
> One person with an M-16 could take out an entire massive army of people wielding spears
I have to disagree. All it would take is for this army to surround the person with the M-16 and wait for a magazine change, then hurl 50 spears at the hapless pincushion. And that's not counting the probability of the rifle overheating, jamming, etc. after long enough.
I realize I am taking this probably too literally, but my point stands :)
You could learn some mainframe stuff using the Hercules emulator[1], but you'd have to find some z/OS installation media somewhere, and I'm not sure if that might infringe copyright or something. Also, JCL is absolutely horrible IMO.
Elixir is not Ruby, it just has a somewhat Ruby-like syntax. The similarities end there. Elixir does not have the performance issues that Ruby has (although it may have different ones!)
Got that. My point was that you are choosing between a language that looks like Ruby and a language that looks like Lisp. That's a big difference and many people, I would assert, would choose one or the other without hesitation. For me, that would be Ruby.
This is false. Studies done in Wuhan show that people with CVD have well over a 10% mortality rate. In addition, COVID-19 has the potential to cause permanent disability if it does not kill you first.
