October 7 attack
Hamas militants broke through the Gaza fence at dawn, slaughtering some 1,200 Israelis at a music festival and in border kibbutzim and dragging 250 hostages back into the strip. The deadliest day for Jews since the Holocaust. Israel's promised retaliation would devastate Gaza for the next year and reshape the region.
GPT-4 released
OpenAI unveiled the successor to the model that had launched ChatGPT, this one capable of looking at images, passing the bar exam, and reasoning across long documents. Microsoft had wired it into Bing days earlier. The pace of AI capability gains had shifted from yearly to monthly, and panic and investment surged together.
Sudan civil war begins
Two generals who had once partnered to overthrow a civilian government turned their guns on each other in Khartoum, plunging Africa's third-largest country into chaos. The regular army and the Rapid Support Forces shelled neighborhoods, looted markets, and emptied hospitals. By year's end Sudan was the world's largest displacement crisis, and the world barely noticed.
Chandrayaan-3 lands on the Moon
India's Chandrayaan-3 lunar lander touched down near the Moon's south pole, a region of permanent shadow and suspected water ice that no other country had reached. Its little Pragyan rover trundled out to sniff for frozen volatiles in the regolith. ISRO's mission cost less than a Hollywood blockbuster. India became the fourth country to soft-land on the Moon, and the first to reach the south polar region.
Brasília's January 6
A week after Lula's inauguration, thousands of supporters of the defeated Jair Bolsonaro stormed Brazil's Congress, Supreme Court, and presidential palace in Brasilia, smashing windows, destroying priceless artworks, and flooding the building with vandals. Security forces, embarrassingly slow to respond, eventually retook the buildings. Brazil's democracy survived; its judiciary, unlike America's, swiftly prosecuted the perpetrators.
Israel invades Gaza
After three weeks of airstrikes, Israeli ground forces rolled into the Gaza Strip in a campaign of urban warfare that would flatten entire neighborhoods and, by some counts, kill more than forty thousand Palestinians within a year. Famine stalked the north, hostages remained underground, and the war's diplomatic ripples reached every continent.
Turkey-Syria earthquake
A magnitude 7.8 quake struck before dawn on a cold February night along a fault no one had adequately warned about, flattening apartment blocks across southern Turkey and northern Syria. More than 59,000 died in the two countries combined. Whole cities like Antakya simply vanished. Turkey's election-year construction shortcuts became evidence in the rubble. Erdogan won the election anyway.
