Probably the biggest reason outside of Biblical prophecy that makes me believe we are in the end times.
Technology is to the point where many of the things predicted in Scripture about the Tribulation and the rise of the antichrist are going to be ridiculously easy to fulfill.
Things like the Mark of the Beast and not allowing buying or selling with out it. Short of biochips, that would be difficult to implement. With biochipping and today’s surveillance technology abilities, it will be very difficult to avoid detection.
Also, the global political situation makes it near impossible to escape detection as well.
A simple, yet massive database, accessed through the internet could validate a QR code tattoo, barcoded # tattoo as to whether one is authorized to buy or sell.
Cell phone towers, satellites in a Starlink configuration, etc.
“Starlink ...... aims for global mobile phone service after 2023” (Wiki)
Localized / regional databases would also work as well.
