    Frankly if teachers are only contributing 1-14% to test scores then I have to wonder why we employ them at all. That's an abysmal number. We could replace them with scarecrows or hobos and still get those numbers.

    While I can at some level understand refusing dropouts, refusing GED graduates is stupid. The GED is basically the outer 'catch' block of the primary school system, and without it, there's no legitimate way to get a diploma if you have unusual circumstances. The fact that some kids use it to 'escape' primary school should tell you that there's either a problem with primary schooling, or that the GED process isn't sufficiently strong - but in both cases, the solution to the problem is NOT to make the GED worthless.

The number of single-patent suits is actually fairly low and even a comprehensive review wouldn't add a lot of workload to the patent office, while the number of suits and patent applications would drop off due to the increased uncertainty of success.

    This is also extremely low priority for me, as it's already happening anyway, and while some part of global violence is related to oil money, there's plenty of other reasons for people to blow each other up. Subsaharan africa and north korea are cases in point.

    > This century is going to see a *lot* of geopolitical stresses as agriculture becomes far less reliable due to the already inevitable climate destabilization.

    Agriculture has always been extremely unreliable, and yearly swings in weather dominate it, not climate change. Climate change is far more gradual than the time needed for agriculture to change.

    > And perhaps most importantly - even if we had fusion mastered today, it would still likely take several decades to migrate the infrastructure.

    Why is this any different from getting any other alternative energy source going?

Compared to what's needed for wind and solar, it's nothing.

    Regarding population growth, most of the growth is in poor countries, where life extension will be less available, and where other dangers still cause a lot of death. While life extension does raise the projected plateau, how far it's raised depends on how fast it hits, how cheap it is, and how stable we're able to make the rest of the world. I'd bet 50/50 odds that the population in 2050 doesn't exceeed ten billion.

    Aging is a horrible thing, something which frankly should not be tolerated in polite society, any more than cancer, alzheimers, and ebola. To simple take it 'off the table' as though it were uncurable and shouldn't be cured is reprehensible.

It's not that I don't see ecological change, it's simply that I don't care about most of it.

    As for SENS, I'm not saying 'cure death'. I'm saying 'delay indefinitely death due to old age'. Why would you think we can't do that? It's a hard problem, but it's not unsolvable. At its core, life is just chemistry.

    Sorry, I should have clarified, as it's somewhat 'inside knowledge'. I meant that the queue was almost perfect in that once you're in it, it's pretty close to FIFO. The reason it's not perfect is because there's sections that are split into subqueues in the middle - there's two subqueues which merge to a single, then split into half a dozen independent lanes that remerge near the highway. (Changing lanes happens, but is discouraged.) The remerge process is also imperfect.

    General FYI regarding your second paragraph: the wait time is never 'almost zero'. Even with no traffic whatsoever, exodus will rarely if ever be less than half an hour to get to the highway. Typical times with no traffic are 45 minutes.

    Otherwise, regarding your second paragraph: putting 3% of the main queue into a priority queue does mean that the priority queue is 3% shorter; however, the wait time for the main queue doesn't depend on that 3% ratio - it depends on the ratio of priority exits to non-priority exits. If 3% of cars enter the priority queue, then it is true that a minimum of 3% of the cars leaving through the exit choke point will be priority cars - however, that's a minimum value, and it's very easy to end up in states where the it can be much larger. Consider a worst case scenario: if the exodus point can only handle 3% of the total load, you end up with all exodus cars being priority cars, and the wait time in the regular queue will increase linearly until the priority queue is empty. There are clearly situations where the wait time for the main queue is increased, and your explanation does not recognize this - it merely states that the increased wait time will be offset by a reduction in queue length, which is clearly false in this scenario.

    Also keep in mind that the exit queues are almost never in steady state, which your analysis largely depends on. They are either 1) empty (parts of nighttime), 2) backing up (7 am through 9 pm some days), or 3) clearing (afternoon and night.) At a minimum, revision of your idea should probably include non-steady-state performance, not just idealized steady state operation. A large yet fixed number of cars must leave through a small, fixed rate gate, and those cars enter the queue at various times with very little understanding of the queue length or expected time in queue.

    If you really want to push this idea, I would recommend creating a set of simulations which show that your idea or some derivative of it does actually work the way you claim it should. These problems are hard, and simulations are considered a minimum standard for good reason.

    ... and this is why I don't feel that you're competent to be suggesting improvements, without having gone through at least one proper exodus.

    The fact of the matter is that the above assumption is largely false - people leave when they have their stuff packed, and once they get in line, they don't get out of line - because there's literally nowhere else to go. You leave when you're ready, usually on the day you planned to leave with the people around you, and you don't have any idea how long it's going to take, you just get in line. If you have to be to work on monday, you have to leave sunday. If one person in your camp of ten has a deadline, then you have to leave at a given time - and that's all there is to it.

    That's not to say that there's no feedback at all for the long lines, but usually that feedback is either premediated (people who leave at 5 am based on the previous day's exodus), or forced (traffic gridlock during peak times). There's virtually none for 'this line is too long, I'm going to wait', in large part because nobody actually knows how long the wait will be, and everyone expects it to be long. Your solution -will- result in globally longer queue times, not because your solution is theoretically imperfect, but because it relies on perfect behaviour of the people in the queue.

    Only the cars in the priority line would have reduced wait times. Because the bottleneck is actually the highway, that reduction comes at the expense of raising the wait times for everyone not in the priority line - unless the lure of the priority queue is so strong that there's enough people waiting for the priority queue to clear the highway bottleneck.

    The only thing that will reduce the wait time in a fair way is to stagger departures more, so that there's lower peak load. Micromananging the current exodus process, a process which is already a nearly perfect queue, will only serve to make things worse on average, in addition to requiring more manpower to manage.

    Frankly, even though you've been to Burning Man, I don't feel you're competent to be suggesting improvements to the exodus traffic problem. You've been there once, and you came in and left on a fast-track bus which was able to bypass the entire process you're trying to critique.
