That's fair. I feel more confident about Google's OSS (like flutter) surviving than I do about Google's consumer products. The flutter community is very strong, and as far as offerings go, it's (imo) the strongest product that abstracts UI/UX development over web and mobile, and the demand for that abstraction is very real.

Plus having Dart (which feels a bit like Java, but less verbose) as the foundation language raises the bar in terms of library code quality (compared to Javascript at least)
