Internet
The internet could be seen as a forerunner of the mark of the beast system.
The internet is a kind of automatic feedback loop between people and the system.
The internet could be seen as a hive mind.
Is this why they are promoting 5G, to connect everyone online all the time.
The mark of the beast system could be implemented using a microchip in the hand or the brain. This microchip could then be connected using WiFi, 5G, 4G , radio signals, low energy Bluetooth.
Do you see how the internet can be seen as a precursor of the mark of the beast system.
This might also cause a kind of spiritual battle occurring for Christians regarding their contact with the internet, whether they understand it or not.
Maybe if Christians understood that the internet is a foregoer of the mark of the beast system it would be easier for them to decide how to relate to the internet.
