so i enter a computer lab due to the massive windows propaganda on campus, as i have a mac, and somethings dont work as good. regardless.. i enter a computer lab, i spot a pc and approach it, type in my user name and password, gives an error. try again, error again, try the third time, third error.
at this point i am thinking i am locked out of the servers here for some odd reason. but then my wireless internet id/pswd works fine on my mac.
im quick to text a friend to find out his username/pswd to access this pc, hes swift to answer back with the required information.
try his.. doesnt work, at this point im sure its the pc. hence i switch to the one next to it, my userID and pswd work fine, and am fast at work.

but then after finishing my work a thought came to mind. this lab has about 70 computer if not more. what if these machines as they are networked decide that we wont work 1 day in the next 2 months, what if they decide taking a break is what they want to do and act on it by denying access, even if the access codes are correct. this frightening tale can be repeated anywhere in the world, why is it that after a while computers tend to act up, granted electric circuits and all, but mate when has that happened to ur trusty clock in ur living room? AI is gaining expertise day by day or maybe its paranoia, u tell me
