Reading some of those time capsules is a gut punch. I know some were naïvely optimistic, but some are painfully ironic:

“[…] You have probably already eliminated all harmful bacteria and viruses and live without ageing or sickness. But it was us who helped you in this, when we discovered the mysteries of cancer and overcame the barrier of tissue incompatibility.” (Tiraspol, Moldova)

Some places now are going backwards in this respect. We have the means to eradicate measles. We had a devastating global pandemic with a catastrophic handling in the US just a couple of years after the capsule opened. If it’s any consolation, the few current communist states handled it well.

“We paid a heavy price of millions of lives for our victory. And today, on 22 June 1969, on the 28th anniversary of the treacherous attack by Nazi Germany on our Soviet country, we address you, those who don’t know what war is. We urge you to remember and respect the memory of those who gave their lives in the fight for socialism, who died defending the freedom of the motherland and European nations from foreign invaders. Guard like sacred relics the monuments we have built to commemorate those who died.” (Okulovka, North-West Russia.)

Not only are there modern Nazis back in the region at war, but many countries, most famously the USA, are fighting a resurgence of fascist-like reaction at the highest levels of power.
