Sending Up-To-Date Computer Stuff Into the Past

This question came up to me a while back, but it still intrigues me. What if you went back in time through a wormhole, time machine, or another means and brought your most up-to-date computer you could bring with you. Lets take an MMO for example. Say you got a specific sword that was released recently, and you went back in time to about 6 months beforehand. How would the game handle that? Or how about going even further back in time to before the MMO was even conceived. Would the โ€œservers be downโ€ for you or would something else happen? These of course are examples, and I am sure you can think of other scenarioโ€™s that are similar.

I moved this to #not-thrive because time travel is not a scientific topic.

From a software engineer perspective, these are pretty simple to answer: the MMO client would contact the server and ask whatโ€™s my inventory etc. So the player would not have the item, and even further back the game would just say โ€œserver not foundโ€ or something. If there was a game that stored the items on the client then, the server would likely encounter an error about the player trying to use an unknown item, likely the server would just cancel the action (or if it was badly made, it might crash).

what if you went back 1000 years and gave the people the most up to date tech would that make us more advanced?

I dont think people in the Middle Ages knew how to use computers, let alone having electricity. You would probably just be burned at the stake for witchcraft.

i mean if you teach them perfectly and everything goes to plan

They still donโ€™t have electricity, the tools and resources necessary to build more or the knowledge to do so. It would last a couple hours and be forgotten in history.

Attempting to teach them would get you arrested for trying to preach your witchcrafty ways, and you (Like fnarr said) would be burned at the stake.
