This is a list of things I hope come to be this decade.
1) The death of ads on the internet. Looking at advertisements becomes much less socially acceptable, and ad blockers become the norm.
2) A properly open source mobile OS takes over.
3) The Linux desktop hits 20% market share.
4) IPv6 replaces IPv4, all but the biggest websites switch over completely.
5) On the back of IPv6, fully peer-to-peer secure messaging takes over. I can now send a full movie to my friends within a group chat, no servers needed.
6) Self-hosting software becomes easy and mainstream (something like yunohost, but not necessarily that implementation). No more command line knowledge needed.
