Visited this one in Sweden last summer: https://www.eketorpsborg.se/eketorp-fort/ Not everything was available/open due to Covid-19. But very interesting place from early Scandinavian iron age. (300 AD).

I switched to IT at 40. Doable. But Swede so a lot of options like paid paternity leave, tuition free university and so on made it easier.

We do have a final long term storage solution for spent swedish waste. Location selected and approved, method tested and the cost has been covered by a nuclear waste fund fee on the produced power. In short it's copper clad steel capsules put in holes surrounded by bentonite clay down in deep shafts dug in stable bedrock. It's probably a waste of good breeder fuel. But it won't leak due to any natural occuring incident in a very, very long time. I think there is information in english here for the curious. https://www.skb.com/ (They have a nice guided tour down in the research mine the did dig to study water flow and chemistry, can recommend it.http://www.skb.com/research-and-technology/laboratories/the-... )

There is probably other ways of doing it, but saying there is no method ready is wrong. I would prefer to burn it again in a breeder and get 500yr waste instead of 50k yr waste. But if we're going to bury it, this will keep the stuff safe for the time needed.

Very true

On the other hand, if we don't get long term immunity from the virus we wont get it from a vaccine either. In my opinion there is three paths through this. Two of them depends on immunity. 1. Slow down the spread with soft lockdown, let it pass and get immunity. Will take a long time. 2. Try to severly limit spread with hard lockdown. Either to open up and do lockdown again as necessary or stay in lockdown. Untill vaccine. This is a long road. Optimistic figures is a vaccine somewhere second half of next year. 3. Contact tracing and severe quarantine for infected and contacts until the virus is eradicated. Quick, only possible if the spread is limited. You can't open your country to others until they have done the same or a vaccine is here. The unicorn exit is of course every county doing this and a total eradication of the virus. A country could possibly change track from strategy 2 to 3 if the spread is down really low and contact tracing is in place. Testing without tracing wont do it.

So soft lockdown in maybe a year or more, deaths will be in the 0,5% vicinity, more in some countries, less in some. Hard lockdown in the same timespan as above. Less deaths but will you have any society to return to? If you do hard lockdown for a while and then lighten up you're in situation 1 basically or forced to lock down soon again. Number three is very attractive. Had we all been prepared and had plans for this like South Korea and being island nations with easily shut borders like NZ it would have been simpler. But most countries were not and are not any of that.
