JetPack could be the death of WP for quite a few devs, and Calypso will be pushed onto devs so they will make addons for that instead of WP itself. Thats what Matt says we should do anyway. Thats the real reason for the whole "learn JavaScript deeply" skit. Automattic seem to want to kill off the competition by using a thousand cuts. Create a closed Apple system. So I suppose the competition needs to step up in order for that to not happen.
