I find it super disappointing that Android, from an operating systems perspective, is so terrible. It's the newest popular operating system but it's no better than Windows, iOS, or Linux. It's a mess of passable API's, average security, etc. Rushed to market for, of course, practical reasons.

I don't see any opportunity in the future for any person or company to take all the lessons learned in the last 50 years and build something new that takes it into account.

Same with browsers; It's only now that we kinda know what a browser really needs to be but there's no way to start from scratch with all those lessons and build a new kind of web browser. There is always going to need to be what they currently are and build on what was already done.

I understand why, but it's still kind of sad.
