The preceding is true to a great extent. But not a total extent.
There's a tradeoff between user friendly and program simplicity. I
don't think substituting underscores for spaces **in filenames** is a
substantial inconvenience for the user.

But that kind of restriction isn't being discussed here. It's a
strawman.

We're not talking about books. Or text files. Or anything except
filenames. Very_few_people_make_filenames_this_long, and if they do,
with a little practice it's pretty easy to use underscore instead of
space.

As long as we're strawmanning, let's go all the way. Instead of issuing
"file not found" when a filename isn't found, we can include an AI
module in every program that decides what the user *really* meant when
typing in the filename. It can analyze every filename on the computer,
perhaps look at its contents, and then decide which the user really
wanted, and open that one. Or, if the file is clicked from a file
manager type interface, the AI can analyze all similarly named files in
that directory and others, and issue an "Are you sure" with ranked
choices of other possibilities.

My point is that sure a computer should be more of a tool than a
slavemaster, but it's a tradeoff, not an absolute. There's a spectrum.

Programming around every conceivable filename increases software
complexity. Let's not forget that simplicity and small attack surface
are assets.

One more thing: One person's "user friendly" is another person's "user
hostile". The "we do it all for you" interface aiding the person not
willing to bend at all to the machine is the "we get in your way"
interface for the person who wants to bend the machine to his/her
workflow.
