The video calls feature of this is a VERY interesting twist: when I'm pairing with someone via MS Teams usually we're just remote-viewing Visual Studio (and pushing/pulling code from git) but every so often it's necessary to share the screen to show what the app is doing or what the logs are doing locally. The video feature, while advertised as "see the face of your colleague" would be really useful for showing the telemetry or screen of the app you're working on together -- without the need for an external conferencing app.

Sounds like Visual Studio Live Share, though I'm pretty sure Live Share doesn't have video calls.

Could you imagine if Amazon acquired JetBrains and GitLab and made "Code with JetBrains, Git/CI/CD with GitLab, Deploy to AWS" easier than doing it any other way they could permanently prevent GCP or Azure from threatening their lead in the cloud.

But that would take vision, charisma, the willingness to take bold steps... so it will never happen.
