Elon Musk is famous for his “move fast” management philosophy, which he demonstrated most starkly when he built new data centers for his AI startup in record time two years ago. But a new team of rocket engineers Musk recently installed to run his data centers is taking a very different approach.

SpaceX is changing how it builds the giant facilities that house AI servers in a way that might slow the building of new campuses, according to people familiar with the situation.

Cursor doesn’t have plans to immediately change the name of its existing tools, including its popular Cursor coding assistant, one person said. The exact timing of the deal closing depends on securing regulatory approvals, though it is expected to close by the end of the month at the latest, they said.
