A Corvette and a Camaro are still vehicles or cars. They have engines. PS4 and Xbox’s have motherboards, cpus, graphics cards and operating system. They are related but a lot less control with consoles. Crossplay wouldnt even be possible if they werent related.
Even cellphones have mothorboards, gpus, ram and storage. Cellphones are computers. Ive studied this shit.
They take out major features of a pc and call it a console.
