That's actually kind of a bug, since Int64 should only overflow at ...807, and the documentation says it's a UInt64 (or a double for fluids I think), which should overflow at ~18e18. Not sure if that's worth a bug report though, since you'll probably never get to these numbers in a proper factory.

I'd say it is impossible for a single human being. It takes magnitudes greater than a lifetime of Factorio running continously in the background to reach the limit of 64 bit.

[edit]

If you run Factorio for 100 years in the background of your computer... you'd still have to produce roughly about 175 000 000 000 Copper Cables per minute. So 175 times what OP did in 500 hours but instead per minute.

If you manage to run Factorio for the next 5 billion years until our Sun exhausted all of its Hydrogen and our solar system slowly fades away... then you'd only have to produce about 3500 Copper Cables per minute.

If you'd do it at the rate of which OP is producing copper cables (~90 000/min judging from the pictures) it would take about 200 000 000 years.

Say hello to the post-human species who will talk about us like we talk about the Triassic/Jurassic extinction event 200 million years ago.


With other words: Fukken impossible.


I wonder if one would actually reach the physical limits and exhaust all resources of the entire map before one would actually reach the 64-bit overflow limit of the production statistics.


Doing the math on stuff like this makes one really think about the fate and purpose of our universe and our existence within it.

• 1X speed: 100 Years
• 2X speed: 50 Years
• 4X speed: 25 Years
• 8X speed: 12.5 Years
• 16X speed: 6.25 Years
• 20X speed: 5 Years (I refuse to go beyond 20X speed, because frankly, this is almost on the level of a quantum computer or supercomputer.)

And assuming that you did make a steady 175 BILLION Copper Cables per minute, I made a list of times that would show the time it would take for each game running at a certain speed multiplier.

I think you'd run out of RAM before your machine uptime mattered.

If you do the math, and assuming that you own a generously beefy computer, and assuming you had a mod installed that allowed infinite ore in ore patches. Taking your equation:

At...

• 1X speed: 100 Years
• 2X speed: 50 Years
• 4X speed: 25 Years
• 8X speed: 12.5 Years
• 16X speed: 6.25 Years
• 20X speed: 5 Years (I refuse to go beyond 20X speed, because frankly, this is almost on the level of a quantum computer or supercomputer.)

For each speed multiplier, add 1-2 years for maintenance, PC restarts, and acts of god (power outages, internet outages, natural disasters).
Still, if you were to run the game nonstop at 20X speed, you would reach the buffer overflow in 5-7 years! That is extremely quick, considering that this is x86-64 we're talking about; this stuff was designed to last when it comes to buffers and variables. Just keep that in mind.
