Don't trust him.

I think a problem is the automatic assumption many young people make that the reason why an older person doesn't use something is because it's to complicated for someone older. I claim that this is largely false, and that the reason why older people don't use the technologies is because they suck, are intrusive, unreliable and fleeting.
Young people are less critical, and seldom think long term (and when they do, they think a year is long term).

Why should an old person learn to use (in rapid succession) CompuServe, AOL, Yahoo, LiveJournal, Myspace, Facebook, Flicker, Pinterest, Instagram (and so on and so on), instead of his relatives putting a little effort into hand written letters and face time?

Better than a Waterstein, I suppose.

Colorado is a city now?

He didn't say the Android Browser, he said the default Android browser.
In newer versions of Android, you don't get the old Android stock browser. It was the default in the past, but hasn't been so for a long time now, and isn't even available unless you run hacks to install it and its dependencies.

That is consistent with trying to balance a needle on its tip.

But Betteridge's Law of Headlines has already answered the question.
The problem is in the very premise. Safari never had anything remotely similar to IEs marketshare. Nor the corporate glue. It's silly to even try to compare what happes with the two over time.
IE was a major enabler and roadblock. Safari was never significant enough to even stub your toe on.

This needs to be funded as one of the faith based initiatives that the last two presidents have pushed.

Rosetta (the craft carrying Philae) took ten years to get there, and required a flyby of Mars and Lutetia to get its vectors and speed right.

And is so small that it's like a fly landing on a townhouse. What's the fly supposed to do? Ask the townhouse to move over?

I'd think it likely wouldn't be enough, because a NEO won't have the mass of Mars which we'd use to brake the craft once there. Unless we were sending an impact missile, it might take a lot of time and planning to get there. Rosetta took 10 years and a flyby of Mars in order to match up with a comet.

I meant all the various giant members of what's commonly/historically known as reptilia, including (but not limited to) archosaurs like dinosaurs, pterosaurs and many of the larger/landbound members of crocodilia and aves (birds).

If you're huge, at least somewhat ectothermic, and can't easily migrate, climate change won't be your friend, and evolution will eventually tally the score as "extinct".
Hm... I wonder whether that applies to Americans too...

Your great-grandchildren probably won't care about your roads and bridges either, other than the cost of repairing them. These days, they're not built like Roman roads and bridges, and don't last for generations.

Not necessarily. We could find a way to jump some of us aside, or heat up one side of it with lasers from afar, or burrow until the crisis is over, or have congress declare it a non-problem, or have religious people pray for a miracle.

I think the simplest solution is the better one. Let them hit. Evolution will take care of the aftermath. It already has weeded out large landbound reptiles that can't take the heat (or the cold) due to meteor strikes. If the Yucatan big boy hadn't hit, there might have been scaly beings in charge now. Other than lawyers, I mean.

I don't think you're aware of just how power frugal the PIII is. The TDP is 27.9W, which is far less than most laptop CPUs burn these days. And given that the average load is in the 0.01 range, it uses far less. It has run fanless since 2003. Energy is not the issue here.

But a point is the reliability of larger die fabs. Can a Raspberry Pi be reasonably expected to run for 10+ years?
Also, the Pi comes with a single 10/100 Ethernet port, running on a CPU-bottlenecked USB 2.0 bus. Just dealing with a normal amount of packets puts a considerable load on the SoC CPU. And no running backups or NFS mounts at GbE speeds.

Don't get me wrong, the Pi was a fabulous little board, but it was never designed for 24/7 network related operations.
And it's certainly not a replacement for a system that doesn't need replacement.

I dunno either, but my main home server is a PIII, running primary dns, dhcp, smtp and a few other services, and average load in the 0.01 range. It's been running pretty much non-stop since 2003.

There's really no need to upgrade just to upgrade, if the box can do its job without breaking a sweat and can be kept patched up to date.

If PIII machines were available and could run the software, why not?
