We are probably at stage 3 which will become apparent in 2024. Most infastructures are decaying and getting worse by the day. This combined with low birth rates and young generations dumbed down by tiktok and bad parenting already paint a bleak future. But there are other factors that will act as a catalyst to what would normally happen in 20-30 years. I give us max 4-5 "good" years. Ofc "us" is subjective, a good chunk of everyday peeps all over the world are already in deep shit, it's just gonna get shittier for them before the real shit storm hits.
