Here we go again! Welcome back to Five Things Tech!

Solar and wind power are on the upswing in 2025, now outpacing global electricity demand—and it’s gotten to the point where they’re making the idea of new nuclear plants look outright silly, given renewables’ new 43% share in electricity generation.

At the same time, Big Tech’s ambitions are getting surprisingly sci-fi, with billions pouring into brain-computer interfaces from neural implants to smart glasses, drawing investors like Altman, Bezos and Gates; but as impressive as the medical potential is, the whole BCI world feels a bit dystopian.

Ukraine is countering Russian “superweapons” not just with high-tech jamming, but with a dose of hacker creativity, using spoofing signals to steer missiles off course—turns out, they’re fighting “advanced” weapons equipped with very dated tech.

Over in Norway, security experts took a Chinese-made bus down into a mine and proved it could theoretically be remotely disabled, stoking European fears about just how vulnerable our imported tech might make us.

Finally, Ireland finds itself dangerously dependent on US tech giants, with their tax tactics and economic impact distorting national statistics and putting the country at risk if trade tensions escalate—just two decades after Zuckerberg casually told me Ireland’s tech appeal was “probably taxes, I don’t know,” the whole country hangs in the balance.
