A five minute YouTube video to get started with a new programming language?
Oh well, we've got different ways, different preferences

Five minutes are enough to learn "Hello World" in that language. Then follows a deeper study.

Why a 5 minute video when 5 paragraphs are enough? Ugh, I can't stand people talking and yapping.

After 230 votes, the span of the results runs from 3.21 to 3.94 (6 of 9 between 3.39 and 3.83).
For this survey, we should have had the counts of each rating 1-5, not just the averages. It would have been fascinating to see which features we all agree about, and which are absolutely required by some, but of no value to others.

I happened to let my mouse cursor rest for a few seconds on the orange bar indicating the average score ... and up popped a small window displaying five vertical bars, labeled 1 to 5. You won't win a gold medal for the formatting, but at least the information is there.
(I guess that this display feature has been around for a long time, but I have never stumbled over it before!)

That's cool. I didn't know this existed, thanks.
- I would love to change the world, but they won’t give me the source code.

Tell my why I should use this language over C++ and C#. If there's any good reason why I should use it, then the other stuff can follow. Otherwise I don't have the time.

In a non-hobbyist setting, that may be be important to you, your company or your customer(s). Frequently (maybe in most cases, this is strongly affected by factors unrelated to the technical language properties, and you are not likely to find it in the documentation on the language.
I've learned new languages: When the company decided to switch to a less used language to protect their IP rights in case the source code was stolen. When entering a new position, and a management decision had been made about language choice before I entered. When getting the responsibility for maintaining existing software in a language new to me. When the context, such as html, restricted the languages available. When a test framework was introduced where test procedures was written in a language new to me. When direct interface to hardware was required, so I had to learn another assembly language. When I had to modify the system build functionality of the 'editor' (well, some people say that emacs is a good OS, but it lacks a decent editor ...).
I have experienced all of these situations. I can imagine several others: A needed library may available only in a specific language (years ago, IBM had some great graphics software in APL). Your customer is buying the source code, dictating your language selection. Your team are experts in a domain specific language new to you. ... We could probably dig up a dozen other examples of restrictions not related to the language itself, but to your specific context.
The language documentation may of course boast: This is the perfect language for everything! without going into any specifics, or only things unrelated to your specific situation (such as 'You can program your editor's behavior', which is irrelevant if your editor is non-programmable or only in another language).
As a hobbyist, you have a great freedom to pick the language of your choice. A small one-man or few-men company restricted to a small class of software, such as small freestanding closed-source applications, interfacing with other software only through IP based protocols (or not at all) may have a similar freedom. And, you have the freedom to shy away from employers expecting you to program in languages other than those you already know.

I fully agree, although I'm pretty sure of the answer most of the time (it isn't better than C/C++, for me).
But recently I'm looking for a good scripting companion to the holy trinity (asm/C/C++) and I found that Julia fills in pretty much those requirements (although in contrast to Python, this language has a huge list of dependencies). I'm always looking for performance and efficiency over ease of use, so the fact that Julia is precompiled (kinda), natively has parallelism (finally) and has basic datatypes (I still can't figure out why anyone could ever want magical-all-in-one-variables, pointers solve everything otherwise).
The languages that remind us of how a computer works are always the good ones. Readability be damned.

Cool, someone who gets it. So Julia:
- Is a good scripting companion to the holy trinity (asm/C/C++)
- Has performance and efficiency
- Is precompiled
- Natively has parallelism
- Has basic datatypes
You missed out this little detail, which is highly important to me:
- Julia has a C API, so is callable from C++, C#, Python, etc
Alright! That's the most important information I need. I now know that stuff can be written in Julia, it will be performant, and it can be plugged into our C# (GUI/Database/Networking), C++ (data models, calculations), CUDA (GPU compute), Python (user scripting) monolith.
Now I can look at that secondary stuff as it's passed the first hurdle.

Well, C++ and C# are powerful but complex languages which lean on huge frameworks.
Sometimes snappier, less powerful languages have their right to be - despite its many issues I still mourn Visual Basic the First because writing testers, simple forms and basically oversized scripts was a breeze.
I found it especially useful to interact directly with DLLs and/or hardware devices, much better than writing a CLI - with a handful of textboxes, a combobox and a few buttons you could test any input to any function and visually show a comprehensive state of the system.

I sometimes mourn the original BASIC ROMS that came on home PCs. It was nice to turn on an old computer and be immediately greeted with a BASIC prompt. You could type:
10 PRINT "Hello World"
20 Goto 10
Run
and Hello World would scroll forever.

I agree, that was wonderful.
But in reality those computers were just toys compared to the modern desktop PC.
The difficult we do right away...
...the impossible takes slightly longer.

I also like C# a lot, but there is no such thing as the best or universal programming language for everything. It always depends on the project and the goal of the solution. The possible paths to the goal are always influenced, shown and limited by the resources that are available.
As mentioned by others, it's not always about performance and efficiency. Often other things get a higher priority, like the target market and customers, or the required compatibility and usability of libraries, tools, or a special environment.
The languages C++/C# certainly ask for good possibilities for desktop or client software projects, but in other areas this is usually not a good choice. To give just a simple counter-example that everyone knows, well-known things are mostly well represented on the web for client/server solutions. For the client, JS (with HTML/CSS) leads, and for servers (outside of cloud solutions) it is still the good old all-rounder PHP.
That is why I am always open to other languages, and I choose what helps best and brings the project work to its goal in the best way.
Something about which we often break our head:
"In the name of the Compiler, the Stack, and the Bug-Free Code. Amen."

I mostly want step by step instructions on how to configure the working environment. And after it the explanation of what and why is needed, and how those are connected.
