That's rubbish. Why should python excel here in biotech related aspects but ruby not?

Note: I am a molecular biologist by trade who went into using ruby primarily. I also use python a lot.

I remember the old HUGO project; lots of that code was written in perl. So why exactly would ruby be unfit here but python would? Please give your EXACT reasons.

I partially agree in regards to javascript; I disagree that there ought to be a hype-buzzword trend. The whole fake AI field ticks me off - they don't understand why they can never achieve true intelligence, yet they keep on claiming it. And people parrot how python will be DOMINATING in the fake AI field. So many fakers.

How many of you guys actually even understand neurobiology?

Also, "dumped" is the wrong word, because you insinuate here that they stopped using ruby altogether. That is not the case; the percentage usage declined in relative terms, but I do not know of any of these companies to have gone down to zero percent in regards to ruby. Which is typical - big companies use all sorts of different languages.

When it comes to speed, they have a point - there is just no contest between C and C++, when comparing it to ruby or python.

In my opinion, though, most of these who critisized ruby and python, are actually also people who are VERY very bad in either of these two languages. Some of them are still stuck with C and perl, too old to learn anything new. And no, the "I'm gonna learn a new language every week" crowd does not count - I have seen too much atrocious coding pattern by these people.

JavaScript is also a partial reason simply because of how important the www became - look at PHP's decline, which is a LOT due to JavaScript.

His online persona has one truth - he spits into communities.

And to compare DHH with Zed is unfair to DHH. DHH never made such idiotic rants like Zed.

Good that I stopped reading the rant when I found out it was him.
