"Computer-education advocates forsake this optimistic notion for a pessimism that betrays their <b><i>otherwise</i></b> cheery outlook."<br/><br/>What's <b><i>otherwise</i></b> mean here? Is it significant in the sentence? <br/><br/>Is it the same as " You have to hurry up, <b><i>otherwise</i></b> you will be last for school?"<br/><br/>What about "Computer-education advocates forsake this optimistic notion for a pessimism that betrays their cheery outlook?"<br/><br/>Please give me some examples<br/><br/>Many thanks!!!!
