The most remarkable things about this announcement: - Electron based app: Electron is a framework sold on the basis of enabling rapid cross-platform development at the cost of performance. - Frontier AI company: AI is sold on the basis of enabling rapid development - App was released in February & took 6 entire months to port to Linux
I was under the impression electron is chosen less because of broad cross-platform concerns and more because chat apps, specifically, require a level of care in text rendering that nobody really wants to design from first principles when they can just piggy back on web technologies. But I wouldn't know first-hand.
1. generally done well by many different UI frameworks
2. generally done better by most popular native UI frameworks than what Electron provides
BUT - those UI frameworks are typically not (very) cross-platform. In that context, Electron provides one of the best unified text-rendering stories of cross-platform options. But definitely far from the best overall.
