I'm out of school for a while. Ivy Tech had issues keeping track of student data. After they lost my data for the sixth time in a month, I dropped out and left (as did about 90% of the rest of the students).
What do you get when you cross a joke with a rhetorical question?

They all missed the first "deadline" for their thesis so they're graduating in August/September on the last possible day that could still be counted as not being the next year.

hypotheses:
1. "new graduates" can be brainwashed/socialized/manipulated to extreme working hours ... for the same pay ... more easily; they are "pliable," and less likely to create "issues" for management.
2. immigration is increasing the number of potential employees who will work for less
3. the number of jobs is shrinking for a variety of reasons including macro-economic factors, the increasing prevalence of using sub-contractors, etc. as a way to avoid companies paying for health-care or any other benefit.

Drop your innocent-coder killing knifes. 
Okay,
When the whole world knows making "+" to concatenate strings does things less efficient than using string-builder, why not the compiler by itself optimize this with string-builder internally?
Compiler folks leave these options open for real men to exercise their performance tuning muscles?
Converting "+" concats into stringbuilder is becoming a standard item in code-review menu.
Slackers in my team love to do these no-brainer optimizations.

string concatenation ain't that bad...
it's when the number of concatenation is random that it's bad (across multiple statement.. worse, with recursion or loop!), multiple temp object are created and buffer values copied again and again.
but a simple
string s = s1 + S2;
is fine!
i.e.
string s = s1 + S2;
is no worse or better than
StringBuild b = new StringBuild();<br />
sb.Append(s1);<br />
sb.Append(s2);<br />
var s = sb.ToString();
but this:
var s = s1 + s2;<br />
s += s3;<br />
s += s4;<br />
is equivalent to
StringBuild b = new StringBuild();<br />
sb.Append(s1);<br />
sb.Append(s2);<br />
var s = sb.ToString();<br />
sb = new StringBuilder();<br />
sb.Append(s);<br />
sb.Append(s3);<br />
s = sb.ToString();<br />
sb = new StringBuilder();<br />
sb.Append(s);<br />
sb.Append(s4);<br />
s = sb.ToString();<br />
which is much obviously worse that
StringBuild b = new StringBuild();<br />
sb.Append(s1);<br />
sb.Append(s2);<br />
sb.Append(s3);<br />
sb.Append(s4);<br />
s = sb.ToString();<br />
and there is no way to optimize that out....
or you have to do like a human, look at the meaning of the code and rewrite it in a different way with same meaning, not sure compilers go that far yet...
particularly when there is extraneous code in between these string concatenations....

That's not quite true. Depends on what kind of analysis is performed. The case you illustrated looks as if each satement was simply transformed into ints StringBuilder equivalent. Multiple pass AST analysis could indeed produce the final result. (I'm not sure writing that code would be worth the effort.)
Cheers!

OK, ok, you might be right!
I do wonder, sometime, how far the fabled "compiler optimization" go!
I know about function inlining, dead code removal, and rewrite 1 mathematical expression...
Not so sure about rewriting the function completely like you suggest though... decompilation snippet across the web don't mention them!.....

The examples you've given deals with a proper variables.
How about temporary string buffers?
Here is a case that demonstrates the goodness of StringBuilder
string returnNumber = "";
for(int i = 0; i<1000; i++)
{
returnNumber = returnNumber + i.ToString();
}
String Vs StringBuilder (C#)[^]
I felt these cases can be picked up by the compiler and optimize it automatically with SB.

It's better to keep the compiler independent of the framework, otherwise you will end up with a dead end full of dependencies in both directions.

I haven't read any of Jeff's posts in quite a while. I think I will catch up a bit in my down time.
Also, Jeff used to be a member of this site before he became famous with Stack Overflow. I don't think he was very active though, here at CP.

Apples to oranges. Production lines don't have software that do 100,000 iterations of string concetinations.

I'm not criticizing you for posting here, but I'd prefer to see questions like this posted in the C# forum. While the C#forum ... imho ... has changed stripes several times over the years, it once was a place that substantial technical discussion occurred on C# language issues, not just an auxiliary QA which it often is now.
I keep wondering about what happens under-the-hood, and about the efficiency of, using string.Format:
string.Format("blah {0} blah2 {1}", "blah-blah", "blah-blah-blah");
cheers, Bill

Java compiler actually does it automatically nowadays. C# one doesn't, AFAIK.
But of course, if you care for performance, use a real programming language

Aaaaaand the whole world is wrong [for making a sweeping generalisation*]:
Jon Skeet investigates[^] - for C# at least.
Oh and
string foo = "bar" + "baz";
compiles down to the same thing as
string foo = "barbaz";
more or less.
