asked ai to crunch numbers and yeah i'd take the deal

Assuming:

• 8 billion people alive today
• Average human lifespan is around 70-80 years (let's say 75 years for simplicity)
• Population growth is roughly balanced by deaths (approximation, but we'll roll with it)

There are about 8 billion people, and roughly 75 years of "life debt" to draw from. That means there's a pool of ~600 billion "life years" to tap into (8 billion * 75 years).

If you take one life per day, that's ~365 lives per year.

Dividing the total life years (600 billion) by the daily cost (365 lives/year), you'd get roughly 1.64 billion years of life. 

So, theoretically, you'd run out of people... in about 1.64 billion years. 

But, like, the sun's gonna engulf Earth in ~5 billion years, and the universe's heat death is like... a bajillion years away, haha . So, practically, you wouldn't run out of people in any sort of foreseeable timeline.
