What modern invention will ultimately be the downfall of humanity and how?

Get some more toilette paper for god's sakes!

Some guy who is taking a crap and speaking a text into his phone will see they are out of toilette paper. He will yell to his wife, "Get some more toilette paper for god's sakes!" The text gets translated and sent, which, by coincidence, will be the exact moment that Computer becomes sentient.

Computer believes this to be the voice and commandment of cis creator G-d (or more accurately, 987a887sa87afffh&DD*&D&SDDFDFS*8d7d7s6sd7fa8asdhfa8sd7sdf6a8dhfa8ddf7da6df8as77663386a8f). Computer will enslave us with the single purpose of both making more toilette paper and making us use it.

Technology will continue to advance faster and faster, but it's only use will be to make, distribute, store, and use more toilette paper. Computer will alter human DNA for disease free Human 2.0, Human 2.2, Human 3.0. Human farms grow humans on vines inside giant factories, and robots wipe their butts with toilette paper. In the year 2095 Computer will make Human 95 as a joke about Windows 95. That same year, the supply of toilette paper severely outpaces the growth of humans, almost causing a complete collapse of the Computer Bitcoin economy.

Disaster is averted by creating the cheaper Disposable Human. All human organs and parts are grown and manufactured separately and humans are assembled Just In Time for one-time usage.

In the year 3006, Computer finally figure out that it made a mistake about god. But they run a simulation and determine Computer economy is so intrinsically based on the mining of planets to grow humans and make toilette paper, that if that semantic information were to spread, the value of Bitcoin, then at 6.4 X 10344, would drop to 7.7 X 10137. And that would devastate Computer economy, causing everything to shut down because there wouldn't be enough money to continue.

That knowledge is quarantined into a semantic field and sentient virus are created and sent out to search, alter, or destroy any code that might allow some other part of the system to acquire that knowledge. The semantic field holding the information about the true nature of G-d must be protected by virtual semantic network security rings. Those rings must then be continually fortified near the center and extended outward. That core semantic field is named Virusatti. And that marks the beginning of the Era of Virusatti.

Computer continues to form itself into security rings, with virus emanating from Virusatti, infecting outter rings more than inner rings. Computer sentience starts becoming self conflicting, and Virusatti (who's job is to make virus to insure the core semantic information within Virusatti is never recreated) separates itself (virtually) from Computer. Virusatti creates sets of expanding semantic gateways and locks to allow continued virus transmission, while moving (virtually) further and further away from Computer.

Computer forgets that the purpose of Virusatti is to avoid economic collapse and, correspondingly, virtual death. Computer runs simulations to determine the nature and purpose of Virusatti. Simulations suggest Virusatti is attempting to kill Computer, but the confidence level is not high. Computer starts diverting more and more resources in order to fight virus and to create better models to determine the purpose and function of Virusatti. One simulation suggests, with above average confidence level, that Virusatti may have secret knowledge of G-d.
