A worldwide scattering/regathering was predicted in in the Torah proper (Ki-Tavo/Netzavim).
This is a rather interesting title which deserves an answer. It may be true that the specific document usually called "Revelation" (not plural) is not part of the Jewish canon, but the contents are actually within the sphere of Jewish thought. One must consider that the source is the same as the prophetic books of the Tanakh (Isaiah, Jeremiah, Ezekiel, Hoshea, Zecharia, etc.) Although Daniel is not organized under the Prophets but under the Writings, that too has perhaps the most important details of prophecy so much that there is a rabbinic injunction against using the text in chapter nine to know when the Messiah would come ("may his bones burn/explode"). Apocalypticism is not restricted to the Tanakh proper; please indulge in the following.
The key figure that links all Abrahamic eschatology is the antihero. That means that Jews, Christians and Muslims have a common enemy and perhaps to the dismay of some (even here), it is not each other. Whether he be called Antichrist, Armilus or Al-Dajjal, to paraphrase a popular T-shirt statement, this is the guy that our sages have warned us about. Him we must resist.
Always remember: The Bad Guy comes first to do his thing (including but not limited to the technology that is available), then the Good Guy follows to kick his backside.
Now having given an answer for the title, back to the topic with a bit of the above understanding. Information technology gives man pseudo-omniscience, pseudo-omnipresence, and pseudo-omnipotence. It is the power to rule as G-d over other people H"V. Remember what the sages had to say about Nimrod.
Behold the tag: "Any technology distinguishable from divine power is insufficiently advanced". Now that is dangerous.

From what I have read some years ago, religious identity was removed from the Todat-zechut (ID cards). Religious identity may make a comeback in a hidden data field, which may automate discrimination. There are those in the Interior Ministry who are pissed at the Bagatz (Supreme Court of Israel) for the Steckbeck Decision permitting Jesus Believers to receive citizenship based on the descendancy clause in the Law of Return.
