That is a poorly worded statement. You live in the present and hope for a future.
Further, I see nothing stopping any of those OS' from supporting future internet standards like IPv6, so I have no idea why you brought it up.
I live in the future, because in my present, IPv6 is not a future internet standard, but one that's already more than a decade old. Or it might just happen that you live in the past, take your pick.
I've been bringing up the issue about IPv6 for more than a decade now, you see I live in the future and my home has been IPv6 native since 2005. Don't believe me? Try searching the Miami mailing lists - Holger Kruse was the only amiga developer ever who ever did anything in regards to IPv6, I was whining about it already back then. The things stopping any of the AmigaOS "spin offs" from supporting this decade+ old internet standard is ignorance, highly optimistic views on what routers can do, and a huge faith in that IPv6 will never happen.
