I think your confusing providence with medical science in the form of vaccinations, blood thinners, and Mr. Dahl's contributions to hydrocephalus relief

Science is great but there are still plenty of diseases and lots of other stuff that leads to tragedies.

If you happen not to have to deal with any of this, it is still just providence.

Chance

Yes, providence is metaphor/personification of luck.

It’s hard for me to distinguish between meant as metaphor and meant literally.

The providence of being here and now, a time where those exist, a country where good medical care is available, and the means to afford it.

A child could die from cancer or from falling while playing, and no vaccination or blood thinner can prevent this. I can understand op's reference to providence in not having to face these tragedies.

I think parents means not dying from measles thanks to vaccines.

One risk less.

Yeah, but his kid died of measles, and his other kid got hit by a car (something that is actually also solvable with technology). Literally every problem discussed in the article was solvable or mitigatable with science or technology, except the political problem of fascism, which was effectively solved by 20 mm cannon fire from Dahl's Spitfire fighter plane.

I don't think they are confusing anything with anything.
