The expected answer means we will have cryptographic security available indefinitely. We may have to keep switching algorithms, but in principle there will always be an algorithm out there that can't be quickly bypassed. Evidence that P = NP (or one is a subset of the other) means all cryptography is doomed to fail.

Comment Re:Roundabout (Score 1) 305

Roundabouts take more physical space (about 4 times as much space) than a straight intersection and don't work well for more than a lane per direction. Besides, we could do better than roundabouts - there's also cloverleaf intersections, but those use roughly a full square mile and require a bridge be built. It just isn't practical for every intersection to have them.

Comment Re:Intelligent Intersections Already Exist (Score 3, Insightful) 305

It's really quite ridiculous we don't have more of them in the US instead of four-way stops and traffic lights.

It's not ridiculous at all - it's a simple space issue. A round about takes more space than a simple intersection with a traffic light. A cloverleaf intersection is even safer and faster than a round about, but it takes even more space and also requires the building of bridge.

Cities already devote enormous amounts of space to the movement of cars. They can't spare any more, at least in the downtown areas. Using round abouts more frequently in the suburbs would make sense though.

Comment Re:Gravity waves != gravitational waves (Score 1) 56

Just a reminder: the gravity waves (waves resulting from gravity restoring an equilibrium) discussed in the article are different from gravitational waves (wave functions describing gravity itself).

In layman's terms it's the difference between waving at someone, and having a seizure. One is an external phenomena caused by gravity, the other is an internal (sorta) phenomena of gravity.

Comment Re:So, tables? (Score 1) 87

What kind of data are you displaying where it doesn't matter if you show it as a 10x10 grid (aka, a table of 10 rows and 10 columns) or as a list (aka, a table of 1 column and an infinite number of rows, which in this case I guess would be 100.)?

The context I meant for "data" above was all the data of the page. Navigation elements in headers, footers and asides. Currently these are positioned using floats and they have to be present in the HTML dom in a certain order for this to work. With grids (and to a lesser extent flexbox) the order the information appears in the DOM isn't relevant.

The example you gave of a 10x10 table isn't the same - it's just a table, not a web document that may need to have its data's presentation optimized for several environments. And yeah, you can set elements to display none and/or double send elements and turn on the one you want for a given view context but that's a waste of bandwidth.

I don't see grids replacing tables where tables make sense. Tables don't make sense as a layout grid mechanism. CSS Grids don't make sense as a table replacement either.

Comment Re:Royalties continue (Score -1, Troll) 87

Do you earn money for the page you developed in 2000?

That'd be like The Walt Disney Company earning money for short films it produced in 1928. Or like Gershwin Enterprises earning money for a musical piece written in 1924.

Oh wait, those are still the case because of the three-generation copyright regime.

How stupid are you? Seriously. The problems of copyright law are entirely off topic and the mediums could not be more different. There's no legitimate comparison to be drawn here so you're coming off as a prattling moron.
