The C that you call "really is better" is not the C which existed before C++. It is "K&R C", which looked like this:
foo (a, b, c)
char *a;
int b, c;
{
/* do something cool here */
}
(*some_pointer) (insert, args, here);
some_pointer (looks, like, a, function);
char *strings = {
"this", "is", "convenient", "isn't", "it?"
};

The C that you call "really is better" is not the C which existed before C++. It is "K&R C", which looked like this: foo (a, b, c) char *a; int b, c; { /* do something cool here */ } And there were no "function declarations" (who needs argument type and cardinality checking anyway), no "slash slash" single line comments, no need to declare a return type as int was implied, say goodbye to const and volatile qualifiers…
by plain old, i think infradig was implying that C was plain and old compared to C++, and not about an older standard of C.

Yes, plain-old C like plain-old vanilla ice cream, as compared to C++ like swirly rainbow vanilla chocolate strawberry template macro class inherits from a waffle cone with generic unique pointer functor sprinkles ice cream.

I'm a C programmer, and I'm considering trying C++ in the future. Can you elaborate?

#7"most researchers prefer an inefficient language because it's easier to get a paper to improve an inefficient language... I've seen dozens of papers on getting lisp almost as fast as C++, on getting Java almost as fast as C++. You can't do that with C++".
A paper from the man himself on getting a type switch in C++ almost as fast as what you get in OCaml. http://www.stroustrup.com/OOPSLA-typeswitch-draft.pdf
Lot's of other places where he's omitting things because he wants to plug C++.
Also, he also seems to be confused between "an efficient language" and "a language that allows you to create something that runs efficiently".

What I've learnt is that if you start writing C++ as a plan-old C, you quickly find yourself reaching for this and that feature from C++ that makes your job easier and your code more readable. Knowing where to stop is the tricky part.

#9I started programming in C++ in the late 90's and I used to be confused about what features to use and found it easy to make a mess.
But I am happy I stuck with it as it opened up opportunities to work in a lot of different and interesting domains like games, mobile apps, interactive art installations, trading systems and video and film processing apps. Also, most of my code is platform independent and very efficient.
There are a few interesting alternatives at the moment, namely Rust and Swift, but for now C++ does everything I want and since C++11 it really feels like a much more modern language.

#10This video was more engaging than I was expecting. To the point that I am not sure what I was expecting.
There did seem to be too much apologizing for how other people messed up the original idea of C++. Same for patronizing much of the industry. I can't claim it was unwarranted, but a lot of patronizing.
