Nuclear has a bad reputation and the small nuclear reactors are much cheaper and suppose to be much safer compared to our old tech reactors. If they keep using existing reactors it's like playing with fire although they are pretty safe to. I assume it's similar as flying in an airplane, in general it's pretty safe but if something does happen you probably have a big problem.
The reason we're keeping old nuclear plants working even after it's safe it's just because it's too expensive to dismantle them. Dispersing the installations everywhere makes it still harder to manage the problems. A nuclear plant is just kicking problems down the road.
It costs a lot to build, recovers the investment in some decades, and then costs a lot (to the public, no longer to the investors) for millennia. And we of course have no idea how bad the residues will be handled some generations down the road.
If you look at plans to switch to full solar + wind they don't look that promising. We have to phase out a lot of existing technology before we're full electric. And even current day grids cannot handle the load or the flexibility solar+wind require (as you have to have a large overhead compared to nuclear). I assume everyone wants a bright and livable future, but everything has to be arranged and in place to make such a transition.
We don't have to replace all our current waste with renewables. We have to halve or more our energy consumption. Renewables are to cover just the rest. With batteries (sodium looks cheap and Northvolt seems up to something in Europe, lithium batteries got 90% cheaper in 10 years, pumping hydro or air or CO2 seems to give longer storage, or flow batteries too, maybe some hydrogen, but I'm not convinced, for energy, still good to research for fertilizer and industry). There are lots and lots of wasted energy. Tourism, crytocurrencies, AI for memes (or for picking targets in Gaza), marketing, excessive design (thousands of versions of the same gadget, some even working, just to confuse and try to sell more), overexpensive films, clothing for just one event, long commutes to work, speculative financing, jets, cars, satellites overcrowding, cosmetics, plastic packaging, cruise liners. Everything has to go. We should get rid of it just for happiness sake, but to add insult to injury, it's killing us. It's intensifying inequalities, heating our planet, polluting our air, plastifying our blood, and boggling our mind.
There are many countries that still depend on nature to provide food an heat for their basic needs, they need to transition with us without first going to burning coal for example. Nuclear reactors also take ages to build, so in short term they wouldn't help either. Having a few countries going CO2 free will not make a big difference if all other countries start producing more CO2 instead.
I'm not sure there are many countries like that. Impoverished countries use oil derivatives or even gas. Anytihing nature gives is stolen to the west, and they get rice, corn or wheat from elsewhere (or BigMacs). And if there still are countries like that I'm not sure they can handle nuclear waste, so they better start planting wind mills and solar panels. Or mills and panel factories.
And cybersecurity, that's still weird to me. If someone wants to break into your system they probably can. And it's all done on computers, so you can probably replicated those results pretty fast. And imagine what consumer AI already can do today... Does cybersecurity still exist at the moment?
No. It may never have existed. It's just that it wasn't such a huge problem when we weren't glued to computer screens all day. I don't think the solution is to improve cybersecurity, I think we need to scale down computer use. Then improve security education (not only cyber, paper signatures can be falsified too), and then scale back up only when we culturally can.
If you require a digital certificate for government interaction to citizens who can't choose, evaluate and decide what hardware and software they trust to generate their own keys, and then you keep their forms in government servers without giving them any cryptographic proof that they sent them, because the government doesn't trust their servers with binding keys, then you're not streamlining red tape, you're just turning citizens into subjects (subject to the state or to the corporations providing clouds, authentication and "trust").
You know cloud services are fake because they can't make rain.
