Electronic devices always have had problems.  They are called glitches.   Scientists have always come upon some type of glitch which worked for the good or the worse with an invention.  Things that happen accidentally have been put to good use, and are still doing that same thing today.  Now, after trial and error, glitches have been resolved to some extent in all fields.

Technological glitches have been known to happen when you least expect them, or want them to.  Voters have been extremely frustrated by the glitches in the voting system of their state.  The machines have glitches that make votes not count due to incorrect tallying.  Some counties have tried to merge in an attempt to help, yet other areas were affected.  Voters had to wait for hours.  Computers control many of our electrical systems.  Airlines use computers, and sometimes glitches occur in that system,  but glitches have also struck in this generation in games.  

Games are computers, and have glitches as well. Not all work for the good, because games have been known to use them to help the enemy of the player.  Some game glitches help the controller by helping their game person overcome obstacles where otherwise would be harder.  There are ways to find glitch answers in the games you play. Check online for answers.  Many of the games played today have a website that will explain how to get over, or past, or renew your life in the game.  Wikipedia has many games listed to refer you to such strategies.
