Hello, and welcome back to TechScape. There was a lot of news last week. To run it down in an expedient fashion:

• Donald Trump, Sam Altman, Masayoshi Son and Larry Ellison announced a $500bn initiative to expand infrastructure supporting artificial intelligence dubbed Stargate. On its heels came a press release from Meta vowing to expand its capital expenditure to $65bn in the coming year to expand its data centers.
