If I understand correctly, Linus was not only dismissing C++, but also the object-oriented programming paradigm. His main concern was creating abstractions that result in inefficiencies which most of us consider not bad enough for writing userland software.<p>What&#x27;s interesting is Stroustrup proudly states that C++ provides &quot;cost-free abstractions&quot;. I&#x27;m not too familiar with C++ implementations; is it fair to say that?
