Ask HN: A New Decade. Any Predictions? (2010)

I was thinking that exact same thing. Rails was hitting its peak in 2010, and the idea that programmer time is more valuable than CPU time suggested dynamic languages were the future.

I mean, that’s not entirely wrong — Besides JS, Python is arguably the most dominant language across all domains. Python is also faster than Ruby, though, and 3.x added static-like features to the language. It doesn’t seem like there’s much appetite for languages any slower than what we have now.

I don’t think one can say that python is faster than ruby: https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

I think the perception is there because of python’s scientific and ML libraries that have a lot of c bindings, perhaps?

Both are drastically faster than they were a decade ago, so 2010-era python or ruby are still the high-water mark.

afaict until the 25 Dec 2019 ruby 2.7.0 release you probably could "say that python is faster than ruby".

Ruby pulled ahead of Python in speed in version 1.9 and has stayed ahead (most of the time, in most tests) since.

That isn't something which can be checked, just stuff someone said.

I wasn't trying to assert that ruby is faster, just trying to correct the notion that python is an inherently faster language than ruby.

If I look at a composite benchmark like debian's and don't see one leading by an order of magnitude, I file that away as "probably about the same speed, depends on your use case"
