Today's Super-computers are having a huge problem right now.
It is easy to have 1000TB of SSD diskspace and 1000 16-core CPU's... the problem they are having now is that the the CPU's can pump out numbers faster than the motherboard's bus, RAM, network and diskspace can save them.
They also have the opposite problem when reading back the data, the disks and network are far slower than the RAM and CPU power. (They always have been...)
A system is only ever as fast as the weakest link.
Unlike 10 years ago, with today's 10Tflop Phi/Tesla processors and 8192qubit quantum computers, the CPU-horsepower is no longer the bottleneck. Read/Writing and sharing data fast enough is still a problem.
There are also non-hardware based problems. For example:
Video game AI hasn't really become any smarter than was possible back in the 90's.
The bots in the newest Halo game are nearly as dumb as the bots in DukeNukem 3D.
Gunning aim is another problem, computers have flawless aim (we have all played against hackbots online), as soon as you round the corner a headshot bullet is flying towards your skull. That's the problem with computers, everything is black or white, they have to program the bots to mis-fire and mis-aim and delay INTENTIONALLY to give humans a fighting chance.
Q: How did that bot know that you were hiding behind that bush or keyhole on the rooftop on the other side of the map?
A: because bots already know the position of all objects and all players AT ALL TIMES, they are programmed to "fake" like they can't see you. They could easily headshot you from across the map in 1ms if the game programmers really wanted the bots to be that good regardless of how hidden you are; bots don't have eyes and aren't looking at pixels on a screen, they have full access to all of the game code.
That's why bots always have better body armor than the human players, because once they make the bot not have perfect aim and "sight", they need it to not be out thunk by the much smarter humans.
That's why it takes 1million knife stabs, 100 bullets and 10 grenades and 3 missiles to kill the end-boss. The game is either super-easy or super-impossible, computers are black and white.
That is why humans like to play against other humans online, it gives them the human-challenge that they just can't get out of their bots.
It is always funny to watch a mixed-level of humans and bots on the same map, the bots always get pwned, they only get a kill when the humans are changing out clips or have already fallen off a rooftop and crippled themselves with 1 bar of life. LOL!
