For future generations :
Bring back cocaine to coca cola.

Since 1904 Coca Cola no longer contains extract from cocaine leaves.

Drugs who made us.
If we live in matrix and we are simulated the general rule would be wipe bugs from the system so ex. if all of people were using cocaine cause they drink coca cola the wipe would be remove cocaine from the coca cola. That would fix the cocaine bug. Cause people in 1904 had almost no knowledge about how world looks like, they were using pigeons to deliver messages. If we bring back cocaine maybe we would also bring back those times, when everyone dropped cocaine in 1939 - 35 years old ourselves were fighting to death between each other cause of rehab.

I wonder how many of those non visual but only statistical bugs we have on this planet. Machine learning is just one of the tools we use to learn about them.
