alt Hacker NewsIf you're in the US, average life expectancy is 79, so it will probably be fine for the next ~5 years.
If you're in Canada, or a G7/EU nation, it's in the 80s, so you may have 10+ years to go, so the chances of Substack being around in the same form for that time period is lower.
Average life expectancy is the wrong thing to use here, since life expectancy _assuming you're still alive at 74_ is actually 13.1 yr in the US.
