Microsoft Edge has been upgraded with new AI capabilities featuring Copilot, aiming to make it the go-to browser for many. The Copilot update enables the GPT-4 chatbot to replace Google Assistant on Android devices, marking a significant integration of Copilot across Microsoft's ecosystem. A new Windows update introduces a colorful Copilot button directly within the OS, anticipated to be used by hundreds of millions of Windows users. The update allows Copilot's artificial tendrils to reach deeper into the OS settings. Despite the removal of Cortana, the latest Copilot update on Android has been met with nostalgia and some criticism, including one glaring problem and reports that it doesn't function seamlessly as a default assistant, especially in its beta version.
