They, ironically, got acquired by Western Digital. But the 'Ultrastar' line name is still alive, if that's what you're looking for. 'Deskstar' seems to be gone, though.
It's a wash. Modern mechanical HDDs are so reliable that the vendor basically doesn't matter. Especially if you stick with 'Enterprise'-tier drives (preferably with a SAS interface), you should be good.
Aside from some mishaps (that don't necessarily impact reliability) with vendors failing to disclose the HAMR nature of some consumer HDDs, I don't think there have been any truly disastrous series in the past 10-15 years or so.
You're more likely to get bitten by supply-chain substitutions (and get used drives instead of new ones) these days, even though that won't necessarily lead to data loss.
Cell diagrams are simplifications. Cells are not like your room with a few things inside. They are more like a decent city. In human cells you have hundreds to thousands of mitochondria.
They don't kind of look like bacteria, there was a lot of gene sequencing and careful examination because it seemed like a very wild theory especially before we've really learned archaea. Quammen's "The Tangled Tree" has a nice writeup on on the process.
The Wikipedia page links to this [0] article as a source, where the table states an estimated 9 billion “ever lived” at the 8000 BCE mark, and 55 billion at the 1 CE mark. The end of prehistory isn’t too well defined, but it’s usually taken to be around 5000 BCE (if not later). So while it’s not very precise of course, from those estimates it certainly looks like more humans lived in prehistory than now, by a few billion at least.
Given that the world population is predicted to peak at about 10.5 billion roughly 60 years from now, it also looks like this won’t change anytime soon.
For comparison there’s still 300,000 Wild West African Gorilla today and they’re extremely restricted in range, share that range with modern humans, etc.
Human populations in prehistory were believed to average somewhere in the 1-15 million range which puts 10B at the very low end estimate with 100+ billion being considered plausible. There was at least one major bottleneck but humans predate the last ice age.
PS: Calling anything history before we have any surviving text to work with is also a stretch.
Written records of events didn’t start everywhere as soon as the first group invented writing.
More relevant when considering the criteria of well documented evidence, a hypothetical ship on an ocean voyage in 1500 is likely to just disappear. Let alone a random West African goat herder in 2200BCE.
Is it not? My kids with all technology and toys they have access to still often choose drawing. And it's not like their main thing or something they strive to get better at. It's just fun.
So definitely no reason to be sad, it is still a great source of entertainment (and not only for the kids)
