I haven't used JetBrains but when I looked at editors a few years ago VSCode had an awful bug where if you had a Mac with a 4K external monitor it would flicker every time you typed a letter. It made VSCode functionally unusable for me. I use VSCode part time and overall find it less intuitive than the Nova UI/UX. Plus every time I have a problem Mike from Panic responds fairly promptly, and they've been responsive to some feature requests for things like debugging node inside Docker containers.
I had similar issues with Safari a few years ago. The situation has vastly improved as most modern sites detect for FIDO2 support instead of just scanning your browser agent.
The founder of the first start-up I worked for around 2006 told me that most of the money and network was centered around Harvard. It was difficult to get funding as a non-Harvard alum.
