Maybe it would be wise to summarize whatever was already mentioned in that thread:

Quote:* Some wouldn't be working in the same field
* The telephone system would be different
* No C programming -> A lot implies from that
* A lot of the backbone of many OS is inspired by Unix so it would have a lot of ramifications

I wonder if the GNU project would have started but on a different basis.

Also for the first part we already had a thread related to that: https://nixers.net/showthread.php?tid=284
I would personally be doing more art, gardening, and psychology.
