Pick whatever you want. Just don't pick a language that is known to be on it's last legs.
It's not as 'trendy' as it once was, but it's better than ever and still widely used.
Do all of these make it faster than PHP?
We'll need to look at it a year or two from now and compare oranges to oranges; the new Ruby JIT (YJIT) is optimized for real world web apps, not for some artificial fibonacci benchmark. Shopify is using benchmarks on actual Rails apps like their store front to see the improvement (https://speed.yjit.org/). If I had to bet I think yes Shopify is serious enough about this to make Ruby faster than PHP - who is working on PHP internals now - Zend? In the end it's mostly a question of how much resources you throw at a problem.
Honestly, I have no idea how it compares to PHP. If I wanted truly fast I'd use a compiled language. The point is more that Ruby is still being used and improved upon all the time; far from 'dead'.
Also I wasn't pointing out what you say, you're reading into it a bit. I haven't used PHP in a long ass time. But it seems like not a bad choice for certain markets, at least as much as Python and Ruby imo
What is this out of the park career path I'd have had choosing ruby? Can you share some more details?
Almost the best advice I can give to a developer is stop being fixated on language, and start being fixated on how to solve business problems, on communicating coherently (and like a human being), and being able to quickly grok complexity. The language you program in is almost the least important part of the offer (as long as you're competent in it)
Where? At Facebook? Or somewhere else?
I’ve heard that exact sentiment over and over since the RoR community aggressively started with their anti-php agenda in about 2006.
So if you need a job you would probably have better chances knowing PHP then knowing Rust. But if in your area is raining with Rust jobs then go ahead and learn only Rust.
