For one thing, the world has an overpopulation problem, so a decline in population worldwide including in America would not be bad for the world in general.

Also, it means there are lots of employment opportunities for those nice Mexicans and South Americans who want to come and stay.

I doubt this will go anywhere as the normal blurb is that the value of your investments can go down as well as up, and risk is proportional to reward. It seems like they were expecting magic to happen with no expectation of risks.

Most of Concorde's flight across the Atlantic was super cruising (without afterburners) and it was and is the only civilian aircraft with this capability. I didn't actually realise this until I started looking around.

If I recall correctly, Concorde did make money once British Airways realised the price people were willing to pay to travel supersonic. However you are correct in that the pricing 'envelope' for profitable supersonic travel is small and possibly unstable.

Concorde was largely developed before computers became widespread.

Fuel is an enormous problem, apart from the cost, there will also be the environmental concerns (Climate change, pollution and even sound)

As far as I know, the only viable contender in the way to fly hypersonic is Reaction Engines SABRE engines, but that seems a project running on millions when it really needs billions of investment.

.. wasn't Google Wave more advanced in the functionality it provided than Slack? What happened to that in the end?

..it's no laughing matter!

Medical supplies seem like they could be a killer app for delivery drones

Phrasing?!!

Instead of directly subsidising Nuclear power, it should be possible to decide the unit price paid for electricity on a number of factors including availability and the carbon footprint required to produce it. This would create a system where nuclear would be a reasonable option for 'base load', and since it's not a specific subsidy for the nuclear industry, more acceptable to all.

It depends - each infringement could mean each potato which infringes, which would make them very expensive potatoes.

My perception has always been not that New Orleans was built below sea level, but that almost the whole damn city has always been one step away from drowning and has simply been a continual effort to prevent it sinking into the swamp from which it arose.

I have solved this by buying 3 TVs of the same type. I can always find at least one remote control and as a bonus there are also fun and games to be had when my partner is watching something in another room.

Whilst paying Tesla may reduced the size of the financial penalty, they are in effect subsidising a competitor. It might be more economic in the long run to pay the EU fine.

Someone should arrest these speeding pulsars in case they crash into something!

In general if you have 2 sensors that disagree significantly, you disable all functions that rely on those sensors and issue an alarm.

You might be able to decide which sensor is correct from data from other systems, but that is another story

Rest of world doesn't believe it
