Is it still necessary to use _ while naming files?

I use command line a lot. I hate needing to add backslashes before spaces or put quotes around file names. It's easier to just use underscores.
Spaces are not the end of the world, but very annoying:
On a bash command line, they make it harder to handle a list of files returned by a command as argument to another.
On the command line (lin or win), they require escaping or quoting when used as arguments or script/executable names.
On many programs, if you cut&paste the complete path to the file (for example in a network drive), you can click on the path and it will access the file, but spaces in filenames or directories breaks that (and it's not bad programming, the program simply can't guess where the link ends).
When you mention the name of the file in a documentation or message, it may lead to misintepretation, and it's just fugly:
"You can find more information in the attached document file.pdf".
What is the name of the file? it can be "the attached document file.pdf", "attached document file.pdf", "document file.pdf" or "file.pdf".
Also when mentioned in a text, the file name may end up split in separated lines or even pages, and will more likely be subject to autocorrect.
When copying the file name in a text, in most environments you can double-click to select the whole name, but it doesn't work if it has spaces.
Now, if you never ever type or copy/paste a file name, and only ever access files through a graphical interface, then it makes no difference.
But then you start getting to comfy and if anything goes, why not non-ascii chars too? And that opens a different can of troubles.
8.3 is horrible in almost any moderately complex system. We have one at work and you basically need a index / translation document to figure out what the files or scripts do. The Database tables have similar short name limits.
You eventually memorize the ones you use often but it creates a huge new / external parties to understand the system.
Also, hasn't been said yet, but when a file name with a space is uploaded to the net, the url will replace spaces with "%20" (for technical reasons), making the URL looking bad
(but still not mandatory to replace spaces by underscodes)
Example: http://example.com/the%20file%2042.png vs http://example.com/the_file_42.png
...But at least it saves you from having to use quotes or escaping out the spaces with \
I'd rather use snake_case for file names in Linux that way you don't have to press shift until the end of the first word, and byt that time you probably have enough characters for tab completion.
TLDR; No
It hasn't been necessary in a long time, unless you're a developer who frequently needs to type in filenames in everywhere (since the command line needs extra protection against spaces and other symbols)
The OS (Windows, Mac, Android, etc) handles thar all for you so you don't have to worry about it (unless you happen to use a badly-written program that doesn't understand spaces, but this is super rare to begin with, and more protected against as time goes on)
Even non-developers may hate spaces in filenames, when links to the file you send in a message don't work because clicking on them uses only up to before the first space.
That depends, if you have the fortune (misfortune?) of using the CAD software Creo/ ProE from PTC then spaces are verboten since they haven't progressed from the days where the software was written for UNIX.
Damn this just made me realize why I use so many _ in my file names. Used to use PTC shit in a previous job very heavily.
To be fair mine only has an underscore because Lemmy doesn't support periods in user names. I have actually barely used the software I was talking about and use another one that doesn't care.
Just in general? No. But I may still use spaces or camel case sometimes on Linux because it makes it a little faster for me to reference a file without escaping the spaces
never use spaces. never use special characters like |$&";?*'. avoid non-ascii. case is preference, i personally use kebab-case
Dashes for dates and ids. Underscores for spaces.

Windows has issues with leading spaces in certain applications, but no, you don't need to replace spaces with underscores in general nowadays.
I'd still advise against it if you're using Windows. A space is interpretered as more than a single character meaning you'll hit the 255 character limit for paths quicker if you have a large folder structure. I've seen this happen many times in my time as a support technician.
