wow, that's quite a lenghty statement. :) I'll just jump in here and there..:

Well yes, that would be an option. Point being, however: I wouldn't _want_ to 
have it disabled. ;) I actually like the idea of that semantic search 
environment, I like the idea of being able to managing resource metadata all 
across different applications and different data types in a consistent, 
straightforward way. My typical example is having a "project context" which 
needs to include e-mails, images, eventually bookmarks/URLs, written 
documents, scheduled appointments, a whole load of different things. So far, in 
most of todays applications, I am almost completely unable to get these things 
together. Mail's on the IMAP server and available to the mail client only. 
Bookmarks are somewhere in a browser. Files of all kind are in folders 
available to, well, file management tools. Adding an information just like 
"this item belongs to project XYZ" _and_ having a clean way of actually finding 
all these again, so far, does not exist. Sure, I could go file level, build a 
project folder and store all the mails, the web bookmarks, the files there, but 
from some points of view this thoroughly sucks: If it works at all - 
appointments, in example, can't be managed this way - or what if items belong 
to different projects? At times, I feel thoroughly annoyed that, even though in 
2013 we do have wobbly 3D accelerated screens, we're not even able to link an 
e-mail, a PDF document and a calendar date together and actually retrieve this 
information across application boundaries. So from that point of view, count 
me as a dedicated friend of the semantic desktop idea. ;)

I thoroughly disagree. To me, even the point of "thinking like a computer" is 
off. End users should have tools at hand allowing to get work done as 
effectively as somehow possible. Nothing more and nothing less. Take tagging or 
timelines: Sorting with vast loads of digital camera images is an annoying 
pain as soon as you are limited to just having at hand all the "features" file 
systems offer (which basically is a hierarchical store with a path and a name). 
You don't have much ways to sort this, as you either are forced into a 
hierarchy which is not too flexible, or you end up with keeping duplicates of 
your data, or you end up with doing symlinks (which no tool so far does in a 
pleasant way). How to keep images sorted in a way so to quickly find all the 
images that have (a) been taken on or around a certain day, (b) feature one or 
two certain persons and (c) are known to be taken in some special place? 
Answering questions like this sucks when all you have is a file system. That 
aside, talking "think like a computer": All the semantics stuff _is_ thinking 
like a computer, too. There's RDF. There's triple stores such as Virtuoso. 
There's SPARQL for querying such information. There's, talking images and PDFs 
and virtually all media files, a whole load of embedded meta information that 
can automatically be extracted, sorted, indexed, managed, provided to the end 
user in order to help him work more efficiently. And what do most of todays 
tools do? They still force users into defining a short file name and storing the 
file somewhere in an on-disk file system. There's so much more possible even 
while "thinking like a computer", but unfortunately, there seems quite a 
problem making people accept these solutions. And, off-hand, maybe the obstacle 
here is not attracting new users new to computers but actually convincing 
those familiar with what computers used to be like, before, that this is 
actually a good thing. ;)

Just my €0.02 of course...
