Conference Talk | C++: A Fast Tour of a Fast Language

https://www.youtube.com/watch?v=dZIeXUvnB0I
This is a lecture about the past, present, and future of C++ that I gave at the SEC and 4Developers' conferences in 2018.

During the presentation, I showed the fat and the gaunt years of C++, why the language currently experiences its renaissance and what modern C++ actually is. Finally, it taught the audience how the language evolved along with its ecosystem and where it will go further.
