It is hard to believe that the famous saying, 'This is the best thing since sliced bread,' only came to pass 89 years ago, when Otto Frederick Rohwedder invented what was'cutting-edge' technology. It is astounding that less than one century later we are on the cusp of driverless cars, consumer drone deliveries, and maybe civilian trips to Mars. Grandiose projects aside, technology has permeated all business sectors – especially human resources (HR). Due to the enormous cost of bad hires -- which Zappos CEO Tony Hsieh estimated has cost his company "well over $100 million" – there has been an HR tech explosion. Artificial intelligence, predictive intelligence and big data have been in the lexicon for years, but as with any emerging technology, it is hard for business leaders to discern which are practical and cost-effective.

Yuneec may be DJI's biggest consumer drone rival, but you probably have only heard of its consumer and selfie drones. The big, six rotor UAV with bright orange visibility is meant for commercial jobs, including video production, public safety, and inspection. It's equipped with a retractable landing gear, mission planning software and a variety of cameras, including a thermal imaging model and one with a two-inch sensor. The landing gear allows a 360-degree, unobstructed view, and the stabilizing gimbal can tilt 20 degrees upward for inspections. There are three of hot-swappable camera options, including the E90, with a 1-inch, 20-megapixel Sony Exmor sensor, not unlike what Sony uses on its RX100 models (there's no mention of 4K support).

Military drones that can fly for more than 40 hours and stream footage of US cities will replace police helicopters by 2025, experts claim. Multiple defence companies are now racing to build unmanned aircraft that will be allowed to fly in US airspace - which is incredibly tightly controlled. Leading the race is a long-winged craft called MQ-9B, created by Californian-based company General Atomics. This could allow law enforcement to stream video of cities from 2,000 feet (50 metres) high using cameras that are powerful enough to pick out individual faces from a crowd. Californian-based company General Atomics is investing heaving in a long-winged craft called MQ-9B and are aiming to receive FAA certification to fly in 2025.

DJI's efforts to improve drone security go well beyond offering bug bounties and requiring updates. The company has rolled out updates to its Go and Go 4 mobile apps in order to pull add-ons that collect too much of your data. The main culprit is JPush, a third-party extension DJI implemented to send notifications when you finish uploading videos to the SkyPixel sharing service. It's supposed to help you move on to other tasks while your video goes to the cloud, but DJI has learned that it's collecting unnecessary info without asking, including the list of apps installed on Android devices. The company says it doesn't approve of this practice any more than you do, and it's creating its own status system as a replacement. The company is also pulling two other plugins, jsPatch and Tinker, that let DJI deliver small updates without replacing an entire app.

Whether or not shark attacks are a major problem in Australia (spoiler alert: they're not), the Australian government has devoted an enormous amount of resources into trying to mitigate the risk of sharks near popular beaches. They've tried nets to keep the sharks out, they've tried electronic gadgets to dissuade them, and they've tried lots of different ways of killing them, without much in the way of evidence that any of it is particularly effective. After six months of trials, the latest and most robot-y idea is about to be implemented: drones will start patrolling some Australian beaches next month, using cameras and some AI-backed image analysis software to spot lurking sharks much better than humans can. We can manage a 20-30 percent accuracy rate, which means both identifying other things as sharks (kinda bad) and misidentifying sharks as other things (way worse). As with many tasks of this kind, a machine learning system does much better: once it's been trained on labeled aerial videos of sharks, whales, dolphins, surfers, swimmers, boats, and whatever else, the software is 90 percent accurate at telling humans to panic because there's a shark somewhere.

DJI clearly doesn't like that organizations are shying away from its drones over security fears, and it knows it can't solve the problem by itself. The company is launching a bug bounty program that will pay between $100 and $30,000 to anyone who finds flaws in its software, whether they're showstopping security exploits, privacy threats, safety issues or simple app crashes. Bug bounties certainly aren't anything new, but this shows how important drone security has become -- DJI doesn't want to lose business or risk an injury because it didn't catch a glitch in time. You can email bug reports to DJI right now, although you'll have to wait a while longer if you want a standardized form and a clearer explanation of the bounty's terms. DJI isn't leaning solely on prizes to improve its security, of course.

Technology changes the world at an accelerated speed and with a force that cannot be pre-determined, as has been shown by the smartphone revolution which took over the world in the past 10 years. Peering under the surface of evolving technologies will show that many technologies are expected to become mainstream soon and will change the world as we know it. Whether it be self-driven cars or drone-based deliveries, many technologies are continuously under development and surface in not just patents, but even in presentations and actual real-world testing. The companies investing in and developing these technologies claim they will be mainstream soon. Self-driven cars: Self-driven cars might be the biggest disruption in the auto industry in the past 100 years.

ABOARD THE USS NIMITZ -- High above the Persian Gulf, an Iranian drone crosses the path of American fighter jets lining up to land on the USS Nimitz. The drone buzzes across the sky more than a mile above the massive aircraft carrier and is spotted by the fighters. But for the senior Navy commanders on the ship, the presence of the enemy drone so close is worrying. Their biggest fear is the surveillance aircraft will start carrying weapons, posing a more direct threat to U.S. vessels transiting one of the world's most significant strategic and economic international waterways. "It's just a matter of time before we see that," said Navy Rear Adm. Bill Byrne, commander of the carrier strike group that includes the Nimitz.

Imagine a warehouse buzzing with tiny drones that automatically track and monitor inventory from afar, leaving workers free to manage and move material. That's the new system developed by MIT researchers, which could prevent mismatches and help employees find particular items faster on top of looking really cool with a bunch of worker drones zipping around. Most importantly, small drones fly around safely as they read RFID tags on inventory from "tens of meters away" with a 19 cm margin of error, according to a report introducing the system. But warehouse-safe tiny UAVs aren't big enough to carry RFID readers that reach such a range -- so the MIT researchers simply made the drones relay signals from standard readers to items and back. That means these little fleets can work with existing RFID-reading systems, software and tags.

Killer robots might be coming for us, but not if Elon Musk has his way. In a letter to the United Nations, Musk championed the cause for 116 entrepreneurs and AI experts to set guidelines for future robots that can make decisions about killing humans. Of course, everyone went into hysterics. The "killer robots" phrase somehow became the norm for many headlines, even though Musk was actually hoping to form a committee (called the Group of Governmental Experts on Lethal Autonomous Weapon Systems). Lethal autonomous weapons threaten to become the third revolution in warfare.
