YouTuber Internet of Bugs examines the latest demo from Cognition that showcases their "first AI software engineer" allegedly solving UpWork programming tasks.

Saudi Arabia’s wildly ambitious plan to build 500m tall, mirrored, 170km long parallel skyscrapers, forming a 1.5M population desert city has been curtailed to 2.4km long.

The news was broken by the financial news publication Bloomberg, which said that Saudi Arabia’s government had “scaled back its medium-term ambitions” for Neom, of which The Line is the most significant sub-project.

The Saudi government had hoped to have 1.5M residents living in The Line by 2030, but this has been scaled back to fewer than 300,000, according to the report. It is unclear how it intends to house a higher concentration of people considering the proposed length (and therefore area) has been massively slashed.

Police say they responded to the incident at Viertola school before 09:00 (06:00 GMT) on Tuesday and urged local residents to remain indoors.

A suspect, who police say was also aged 12, has been arrested.

The school has 800 students and 90 staff. Witnesses told public broadcaster YLE that two ambulances had left the scene.

In common with other Finnish schools, children had just returned to classes in Vantaa, north of the capital Helsinki, after the long Easter weekend.
