The guy doing this video is a tool. I couldn't get past his idiocy of Objective C. I've pooped out and forgotten more about NeXT than he will know in this or the next life time, yet cant manage the stupidity yet arrogance ratio this tool manages. Pass.
I confess that I also tend to give this guy's videos a pass. Some of his content suggests there's real competence behind the smarmy dismissiveness—if it pertains to something he's used in his career—but mostly it's crud.
