[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**

Q:

Why is that the --cached flag seems to refer to different memory in different git commands?

Why does git rm --cached remove files from the "index" or "stage", but git ls-files --cached list files not from "index" but from the current commit.
I have to use git ls-files --staged to list the files in the "index".
I thought the cache, stage, and index were the same thing. Why is that the --cached flag seems to refer to different memory in different commands.

A:

Although this isn't really a programming issue, it is one of the classic Git gotchas.
Some Git commands take --index flags (git apply in particular).  Some accept --cached and --staged as synonyms (git diff in particular).  Some use --cached only (git rm) and some use --staged only (git ls-files).  Why?  (Note: answers to this sort of question usually involve history and/or philosophy.)
As phd noted in a comment, "creating consistent user interface is not [a Git] strong point".
There is a Git entity, normally stored in a file—.git/index is the most common one—that Git variously calls the index, the staging area, or (sometimes and now pretty rarely) the cache.  There is a separate entity that exists only at run-time inside Git programs that is also called the cache.  The confusion of the two names is why "the cache" is now mostly reserved for the in-memory data structure.  So we should call the other one—the on-disk stuff, that's found in .git/index or perhaps elsewhere, the index, to refer to what it is named and where it resides, or the staging area to refer to its main function.
Its main function is that it acts as the proposed next commit.  A Git commit always has a snapshot of some set of files, plus whatever metadata is appropriate.
If you make a new commit, the new commit has your name and email address as the author and committer, "now" (as determined by your computer's clock) as the date-and-time stamps, and whatever log message you supply as the log message.  The new commit's parent(s) are set automatically by Git as appropriate.  Some additional information, such as the commit text encoding, sign-off lines, GPG signatures, and so on might also be in the metadata.  So this is where the metadata comes from: mostly from you, with a bit supplied by Git itself.  But what about the snapshot?
Git makes the snapshot by turning a set of files—file names, modes, and content—that are stored in the index, into a frozen set of files stored in a commit.  (Technically, each files' content itself is already in the repository, in the form of a Git blob object, but we only see this when we delve into the details of individual index entries.)
We check out some initial commit, making it the current commit, in order to work on it: git checkout master or git switch master, for instace.  Git copies the selected commit's files into the index, so that the staging area—the index as viewed as the proposed next commit—matches the current commit.  Git copies the index's files to our work-tree, so that we can touch and smell the files, or whatever it is we do with files stored in their normal form—the files inside a commit are in a special, read-only, Git-only form that the rest of the system can't use at all.
Then, we fold, spindle, and mutilate the work-tree files to our heart's content.  When we're done with this and wish to make a new commit, we must replace the index copies of files.  Using git add is the easy way: Git will copy the work-tree version of the file back into the index, replacing the ready-to-commit Git-ized frozen-format version.  Any files we do not replace here remain in the same form they have had since we extracted them earlier.  So this arranges the index—stages it, in other words—to be ready for the next commit.
So that's where the names came from.  But why are the flags inconsistent?  The only real answer here is history.  The term stage came about later.  The name index was in use from the start.  It's obviously not such a great term: it's too generic.

On being indexed: I will not be pushed, filed, stamped, indexed, briefed, debriefed, or numbered.More on The Prisoner

The fact that the index acts as a staging area probably led to the term staging area and the --staged flags—although in fact, the way merge works clearly predated this.  During a conflicted merge, the index expands from having one copy of each file, to having (up to) three.  The three copies are from three different commits, and they get numbered.  These numbers are staging slot numbers.  Staging slot #1 is for the merge base, slot #2 is for the "ours" file, and slot #3 is for the "theirs" file.
You resolve a merge conflict by erasing the nonzero staging-slot-number entries from the index and storing a staging-slot-zero entry for the file instead (or removing everything entirely, if the file is supposed to not-exist in the new commit).  Again, git add does all this work for you, the easy way: there is no need to fiddle with git update-index these days.
There are occasional attempts, as in git apply, to distinguish clearly between "just what's in the index" and "what's in the index and the work-tree".  For instance, according to the git apply documentation:

--index
      When --check is in effect, or when applying the patch (which is the default when none of the options that disables it is in effect), make sure the patch is applicable to what the current index file records. If the file to be patched in the working tree is not up to date, it is flagged as an error. This flag also causes the index file to be updated.
--cached
      Apply a patch without touching the working tree. Instead take the cached data, apply the patch, and store the result in the index without using the working tree. This implies --index.

That is, --index means touch (modify by patching) both the index and the work-tree and --cached means touch only the index.  But git ls-files and git diff do not modify anything, so they don't need this kind of distinction.
Really, I think both terms are not that great, but they have been defined this way for over a decade.  We are pretty much stuck with them.
