[ WP ] A time traveler goes to the 1920s and drops a modern day Smartphone . How does this change history ?

`` Another one just popped, deploying the agent.'' 
 `` Again? I do n't really trust that one.'' 
 `` You're not supposed to'trust' that one. It does n't matter anyway, he's already escaped and hurtling towards the target''. 
 I had already escaped and was hurtling towards my target. My job in that time period was to prevent any chance of quantum looping from occurring. That means I prevent the unnecessary advancement of society. The target I was looking for was a scientist who had lost grant money for a time travel experiment. He had gone AWOL and finished the project, without any of the proper safety measures. The activation of the machine had resulted in a large explosion which replaced his lab with a small section of jungle that had been populated with dinosaurs. The target aimed to travel to the 1920s, where he would deposit a personal data assistant among the general population. His lack of safety in this procedure, however, resulted in his death upon entering the portal. When I began my mission I appeared somewhere under New York City. Reports had suggested that he had landed somewhere in the mountains. A brief flight to a `` meteor crash'' had revealed nothing much. The target had disintegrated, along with his technology. All that remained was a smoking pile of rot with bits of melted metal pouring out of it. Evidence of the metal was to much of a risk to let go. Corpses can be a burden to travel through time, so I thought it best to do something simpler. I'd let him travel on his own. The minute the portal opened I hurled his body through. Doing that would create a worm effect. His body soon broke into a series of particles that would be scattered all across space and time. I radioed back to base to confirm target neutralization, but all I had heard was static. 
 `` Figures,'' I muttered to myself, `` That incident was what caused the formation of the P.U.A.S. Those idiots just prevented themselves from being born.''
