Time was, the worst news you had to worry about getting from Bill Gates was that Windows '95 had crashed just as you were about to win the FA Cup on Championship Manager.
Now the benevolent Geek King has issued a far more alarming error warning, not just for your PC but the future of mankind itself: a bioterrorist attack that could wipe out 30 million people is becoming 'increasingly likely', reports the Telegraph.
The Microsoft Founder, whose charitable foundation pours millions into spotting outbreaks of deadly diseases, warned that the spread of a lethal respiratory virus like smallpox would do more damage than even a nuclear attack like that one currently being pondered by psycho man-baby Kim Jong-un in North Korea.
Speaking ahead of speech at the Royal United Services Institute in London (RUSI), Gates said: "Bioterrorism is a much larger risk than a pandemic. All these advances in biology have made it far easier for a terrorist to recreate smallpox, which is a highly fatal pathogen, where there is essentially no immunity remaining at this point.
"When you are thinking about things that could cause in excess of 10 million deaths, even something tragic like a nuclear weapons incident wouldn't get to that level. So the greatest risk is from a natural epidemic or an intentionally caused infection bioterrorism events."
OK. Deep breath.
Bill continued: "Whether the next epidemic is unleashed by a quirk of nature or the hand of terrorist, scientists say a fast-moving airborne pathogen could kill more than 30 million people in less than a year. So the world does need to think about this."
Yup. Will do Bill, probably right before we try and go to sleep tonight.
"We will have epidemics in the next 20 years far worse than the ebola epidemic, or the Zika epidemic and there is some chance it would be a form of flu," he went on.
"Something that is human-to-human respiratory that is like a measles or a flu or smallpox, that you need just one person on the bus or plane or the airport and you get huge things. A health crisis somewhere is a health crisis everywhere.
"So the scariest thing is something like the 1919 flu which really spreads everywhere and because people are moving around more it's easier for it to spread than back in 1919. If 1919 came back we have no immunity to that strain."
Members of the 'why do we send all that money to bloody foreigners when it could be spent in this country' brigade may want to listen up for this next bit: Mr Gates went on to urge Theresa May to maintain the 0.7 per cent GDP we currently pledge to foreign aide.
"The UK's foreign aid investments are, in fact, long term investments in the health and security of British citizens here at home," he said.
"A disease is more likely to become an epidemic when countries are unstable and have no functioning health system. We can't build a wall to hold back the next global epidemic."
Wise worlds for troubling times.
