I noticed that both in live talks and in the streams introduction text, the author uses the term "monotonically increasing" for the IDs autogenerated by the XADD command. However the term is wrong, since monotonic would imply that two consecutive IDS could be the same, whereas the author most certainly means "strictly increasing".
to clarify: monotonically increasing would be the timestamp part of the ID, but since it has a counter postfixed, the ID itself becomes strictly increasing.
