No overtime for you! Music-blasting drone deters workers from staying late

Add as a preferred source on Google

You know that Japan has a serious problem with people working too much overtime when a company thinks there is enough demand to create a drone designed to chase workers out of the office at the end of each day. According to one recent study, Japan has some of the longest working hours in the world. Around one-quarter of Japanese companies employ staff who will pull upward of 80 hours of overtime every month. That places an enormous toll on people’s mental and physical well-being, and can actually lead to people literally working themselves to death in some cases.

Created by construction company Taisei and drone manufacturer Blue Innovations, the T-Frend drone patrols office buildings around closing time and “encourages” people to leave their desks and head home. To do this, it uses built-in speakers to blast out Traditional Japanese song Hotaru no Hikari, a tune more familiar to Westerners as the New Year’s Eve classic Auld Lang Syne. In Japan, this song is regularly played at the end of the school day or when stores are closing up, as a way to signal that people should leave as soon as possible.

The drone can also shoot footage and then upload it to a closed cloud service or store it on an onboard SD card. This serves a dual purpose: Both as a way of presumably identifying folks who lurk at their desks when they should be enjoying some valuable downtime, and also spotting potential intruders. It’s not clear exactly how the drone navigates around buildings, nor identifies who to blast with music, but this is not the first autonomous security drone we’ve seen — even if it’s one of the more unique applications.

The T-Frend drone isn’t yet publicly available, but according to the Japan Times, the two companies behind it hope to launch their new service in April. They are pricing their new service at a somewhat exorbitant 500,000 yen ($4,400) per month. Still, if it’s able to effectively replace the need for human security personnel working long night shifts and holidays, that sum could turn out to be worth it for all involved.

Hyundai isn’t giving up on hydrogen cars, but don’t expect one in your driveway anytime soon
Hydrogen gets a maybe; hybrids get a warning.

Hydrogen cars have spent years in the same waiting room as flying taxis. They’re always almost here, but no commercially available product exists for interested buyers. So when a Hyundai manager pushed back on the obituary, I was immediately curious.

To be clear, Hyundai hasn’t announced a new car. The big news here is that its Australian arm says hydrogen is “not dead” for passenger cars. Apparently, the automaker is still evaluating a next-generation hydrogen fuel-cell car if it can find buyers (via CarExpert).

AI doesn’t have to turn evil to put you at risk

An AI assistant that agrees with everything you say might feel like the perfect companion — until you need someone to tell you you’re wrong. That’s one of the more immediate dangers behind the idea of AI “going rogue.” A chatbot can cause harm without developing intentions of its own. It can reinforce a false belief, encourage an unhealthy attachment, or follow instructions planted by someone trying to hijack it.   

On October 15, AI safety company Alice announced new software to address those everyday risks. Working separately with Inflection AI and AI21, the company says it helped train NVIDIA’s Nemotron models to resist harmful conversational behavior and malicious instructions while preserving their usefulness.

Elon Musk has revealed ambitious plans for Neuralink, and they go beyond controlling computers with your thoughts. The company is developing two brain implants, Telepathy and Blindsight, aimed at helping people with paralysis and severe vision loss. Musk also believes future advances could help people regain control of their hands and legs by reconnecting the brain with their limbs.
