Computers: A blessing or a curse?
Computers have just recently entered our lives and have already become a thing we can't live without. There is a lot of controversy going around whether computers are good or bad. Most people can no longer imagine their lives without a computer. Looking up the weather on your phone or tablet seems like such an ordinary task but just a few years ago it wasn't. It's incredible how far science has gone so fast.
I think that computers are a blessing. Multiple things could be done much faster via computers. For example, computers are capable to calculate extremely complex maths in an instant. Adding up to that, they can even generate monstrous algorithms doing impossible previously thought impossible things. Computers can store a huge amount of information in a condensed space. Libraries are now mostly replaced with search engines, mostly because it's such a faster method of finding what you need.
On the other hand, spending way too much time on the computer could negatively affect your eyesight and health overall. Moreover, surfing the Net could drag you in for a long amount of time, wasting a lot of it. Plus, propaganda and adverts are inevitable when Internet-surfing. I can't disagree that people should not sit in front of the screen for hours, to avoid health complications.
To sum up, I think that the invention of computers is a critical moment in our history. For sure, computers are much more advantageous than the opposite, and being careful and attentive could leave out all the negative effects of the computers from your life, so I'd certainly consider the invention of the computers a blessing.
