Indeed, and C++ was initially a preprocessor (CFront) by Stroustrup, dynamic dispatch was considered too slow at the time, so c++ style objects and methods were faster and as a faster version of simula [1]. Objective C was an alternative that used something closer to smalltalk but it was slower and a few years later. C++ was first released in 1983 internally at AT&T, and for perspective, the 286 was released around the same time with a clock speed of 8 MHz.
