The primary difference between computer code then, and computer code now, was then, the PROGRAMMER had to manage memory access. Coding was very tight, very efficient, and precise. Coding now, literally any idiot can code something now, and the environment automatically handles memory allocation, access, and destruction. Since the environment is handling RAM, and has to be both safe and effective(lol), both it's safety and it's efficacy have to decrease to accommodate the dynamic environment of a modern operating system, on variable and unknown hardware types. It's lazy programming in a highly dynamic system that is running numerous threads on numerous processes all using the same bank of RAM. That's seriously all it is. Coming from a former assembly language programmer, who is now a high level language coder, I know this to be the case. The system used to send people to the moon, was tight, precise, and served one purpose. It's akin to what we just saw in Afghanistan. You can train 300,000 men to do their individual tasks, and give them the equipment to do it, but if it isn't well organized and well maintained, it fails. Send a couple hundred of our best people with our best equipment, with a singular task, and we could probably take it back if we wanted.
