Umpires using technology

For as long as technology has been around that can influence umpiring descisions so has the debate on whether or not we should use it, or moreso how often we should use it. Wrong descisions can turn test matches and destroy players careers. Yet through we still don't use hawkeye, hotspot, snicko and other peices of technology to influence our descisions. Some say well if we have this technology why don't we use it but I beg to differ. Years have gone by without argument. Only has it been in the last few years that we have developed this technology. Cricket has been played for decades upon decades and only now are we complaining about wrong descisions and why? Because we believe we have the technology to make right descisions. What about the days of Don Bradman and the days of Clive Lloyd, two periods where two different nations were somewhat invincible and why, not because they had dodgy descisions but because they were the best. Today this is the same, generally the team we know is better comes out on top. There is no real reason to use this technology for reasons other than training, development and entertainment. As long as you have an impartial umpire you have a fair game, good competition and great entertainment. We need not get caught up in detail, lets focus on playing cricket.
