computer and its typographic errors!

Computer and its typographical errors is a serious issues that call's for concern!imagine a student who is taking her final year course exam in English language, who undoubtedly had performed creditably well in all her previous exam's in English language but failed her final year exam due to computer and its typographic errors in terms of computer inputs or words u never bargained for!imagine u writing a letter to ur dear father who was supposed to pay ur last term sch fees but failed to do so because he had not received his 3 months monthly salary .however,The content of ur letter was to inform him that u had just be sent out of sch since u where unable to pay up for ur last session school fees.now,ur father had prepared his mind to read ur letter and begin to identify some grammatical blunders unreasonably imputed by ur computer,would he still have the mindset that his son  is doing very great in his studies?imagine when u wanted to write or type "have ,and ur computer had forcefully made an inputs of "has,instead of have.now imaging a situation where u wanted to type" six,and ur computer is given u sex instead of six and the letter gets to ur pastor,how would he perceived ur personality? I said this for the educated ones to understand but the illiterate ones may never understand. Some people are just there to pick out ur human errors but failed to understand that some human errors are some times caused by some unforseen higher forces!A word is enough for the wise.
