In the 90s it may have been true - windows was focused on user experience on the desktop. Pre- internet, security just wasn't relevant.
Even in that era though, Linux was running on servers in universities et cetera managing many users.
I guess this is where the reputation arose.
These days I don't think either is inherently more secure than another in a general sense.
For specific uses cases one might be more "reliable" than another just because it's used more and therefore has more people looking at it. For example, the vast majority of Web servers are in a Linux environment, but the vast majority of on premise email servers would be Windows.
What I'm saying is, in 2024 the general security of each platform is going to be comparable, and only a very small component in your chain of reliability. Like if you develop a threat model, and write policies, and maintain behaviours in practice, the underlying security provided by the environment isn't really that relevant.
I think the option of nuclear needs to be on the table, and in some (or many) circumstances it might be the best fit.
Presently in Australia one of our two major parties is campaigning on a "pivot to nuclear" platform, but we're kind the polar opposite to the netherlands (both figuratively and literally?). The vast majority of Australia is sunny desert, girt by sea, with a tiny population in on the coast. My state is something like 2,000km by 1,250km, with about 2 million people. Nuclear just doesn't seem like a good fit right now.
My concern is that with this pivot to nuclear we basically just keep burning coal for the next 20 years while we're building nuclear plants.
It might be a great idea to build several reactors, while we furiously build out wind and solar.
There are some gargantuan solar hydrogen cracking projects not far from here in the planning phase which just sound amazing to me.
What's done is done. From day 1 after the referendum it was obvious to everyone that the UK would spend the next 50 years trying to mitigate the impact of that ridiculous decision. Hotting the "rejoin" button is not necessarily a short cut to the end.
