Well, no *one* of us in a position to save the coral reefs. Not even world leaders can do it. But we *all* are in a position to do a little bit, and collectively all those little bits add up to matter.

Sure if you're the only person trying to reduce is carbon footprint you will make no difference. But if enough people do it, then that captures the attention of industry and politicians and shifts the Overton window. Clearly we can't save everything, but there's still a lot on the table and marginal improvements matter. All-or-nothing thinking is a big part of denialist thinking; if you can't fix everything then there's no point in fixing anything and therefore people say there's a problem are alarmists predicting a catastrophe we couldn't do anything about even if it weren't happening.

As to the loss of coral reefs not being the worst outcome of climate change, that's probably true, but we really can't anticiapte the impact. About a quarter of all marine life depends on coral reefs for some part of their life cycle. Losing all of it would likely be catastrophic in ways we can't imagine yet, but the flip side is that saving *some* of it is likely to be quite a worthwhile goal.

Of course this isn't science, it's just wishful thinking and hand waving about things you don't actually know much about. It's probably worth noting that actual reef scientists aren't so cheerful about the prospects for coral reefs as you are.

It's not even that what you *think* you know is necessarily wrong. You're talking about about something reef scientists aren't particulary worried about: the extinction of coral *species*. In other words it's a straw man. What scientists are worried about is something quite different: a massive reduction in the 348,000 square kilometers of coral reef habitat that currently exist.

That's something that will take millions of years to recover from, and which will cause countless extinctions It will result in multiple species extinctions; sure that's survival of the fittest, but "fittest" doesn't mean "better"; it means more fitted to specific set of new circumstances, in this case circumstances we *chose to create*. And sure, in a few million years it won't matter. But that's not the test we use to decide whether anything other issue needs addressing. If someone broke into your house and took a dump on your kitchen table, it wouldn't matter in a million years, but you'd sure report it to the cops and expect something to get done about it.

No, it's not evolution *at work*. It's human intervention in the environment at work. Sure, evolution will *respond* to this intervention; if you want to see *that* at work, go into suspended animation for a hundred thousand years.

You could argue that *humans* are part of nature and therefore anything we do is natural. That's just quibbling. By that argument it would be just as natural for us to choose not to shit in our own beds.

Turbotax offers free service to low-to-moderate income people as part of an agreement it has made with the IRS. In return for this, the IRS doesn't provide free electronic tax preparation services like most other advanced countries do. For most consumers, the IRS could in fact automatically fill out their returns and the consumer could simply check it by answering a few simple questions rather than puzzling over instructions written for professional accountants.

If you've always wondered why filing your taxes couldn't be simpler, a bit part of this is marketing from companies like Intuit that make a lot of money out of simplifying the process for taxpayers.

The free tier service is something Intuit is contractually obligated to provide. Upselling low-income people to a paid service that wouldn't benefit them in any way is morally dubious at best.

Comment Re:Just let them use AI (Score 2) 115

I don't think that the point of writing assignments is to produce documents as a product. It's to have the student go through the process of gathering, analyzing and understanding the material, in order for them to learn it. If they skip that work, they learn little or nothing.

In the real world, being effective in directing a computer to produce a bunch of text that you know nothing about is not a worthwhile skill. If someone comes back with issues related to the AI-generated content, how would you address the problems if you're mostly ignorant about the topic at hand?

Comment Re:A Walkable City? (Score 1) 199

You want a pre-WW2 suburb.

I was visiting Oxford UK on business and I stayed at a colleague's house which dated from the1800s. I was shocked that the front door of her house was right at the sidewalk, you could look right into her front room. But it turned out that by giving up privacy in that front room, she got an enormous and very private back yard. The arrangement was something like this. That's just a street in the area I randomly picked off of Google Maps satellite view, but I checked it for walkability: it's less than one minute's walk from the local boozer, and on the way back you can get a takeaway curry.

I'll quote from the Wikipedia Article: "In urban planning, walkability is the accessibility of amenities by foot." It is important to contrast this with the practices it was intended to counter (again from the same article): "... urban spaces should be more than just transport corridors designed for maximum vehicle throughput."

Transit is an integral part of walkable planning simply because it gets people *into* neighborhoods so they can do things on foot. But cars are a way to get people into an area too, so cars can and should be part of *walkability* planning. For example there's a main street area near me with maybe 50-70 stores. When I visit I contribute to congestion by driving around looking for a parking spot. A carefully placed parking lot could reduce car congestion on the street while increasing foot traffic and boosting both business and town tax revenues.
