Text 1 When I started my careef I was astonished by how superhuman some Fortune 500 executives were.It seemed they were magicians.Every decision they made based on deep market knowledge and up-to-date information.How did they do it?Thcy have marketing teams that can pull research together in hours.They have chiefs of staff who give them carefully crafied agendas for every day.These teams give Fortune 500 executives what appears to bc super-human knowledge.Foriunately for those of us who don't have Fortune 500 budgets at our disposal,it's getting easier and casier to build your own secret support staff.Within five years,most executives at any size company-and,indeed,most knowledge workers-will have tools that do much of the work of a CEO's private group.That is, Cyborg systems, or what I called agents .It will make this possible,using a blend of learning algorithms and distributed labor to perform an ever-widening range of tasks at low cost.With help from these agents,we'II be able to look as smari as those CEOs do today.I got one taste of this when I started using Wonder.Wonder is like having a personal researcher,deploying a small army of experts,including trained librarians,to do small,defined research projects for me.I ask Wonder for help.For$30 to$60,Wonder saves me hours every week.More and more products and services will fuse machine intelligence with crowd work to help users get things done.To be clear,CEO support teams aren't going away.Top executives will continue to see benefits from dedicated,trusted support staff who can handle difficult,urgent,delicate work.But machine intelligence systems can take on elements of what these people do at a much lower cost,democratizing many of these capabilities.Granted,there is going to be a lot of garbage before we realize the full promise of these virtual support armies.Many ofthem fail to live up to even basic promises,like this weather bot that has trouble telling you about the weather.But if you can filter through the many new offerings to fmd valuable tools,your work will improve and you may even start to look like those CEOs with the seemingly.Executives in small-size companies can work as Fortune 500 CEOs by_____.
A.hiringmoreknowledgeworkers
B.dependingonsupportingstaff
C.gettinglowercostlabor
D.usingmachineintelligence
