It appears that the Big Bang came from nothing. EVERY SIMULATION always starts from nothing whenever the simulation program starts running, Our universe has a speed limit. It is the speed of light. That is a fact, but nobody knows the reason why the speed of light is any particular speed and not arbitrarily faster or slower. EVERY SIMULATION also has a speed limit. It is the maximum rate of execution of the program. Life and the various lifeforms appeared suddenly. In EVERY SIMULATION new things come into being, where nothing like them existed before.

You clearly haven't played very many simulation games. Any decent implementation of Conway's Game of Life has an exception to all of your absolute statements, for example.

Even if the simulation has bugs, we wouldn't know it - because there's nothing to compare to.
If properly sandboxed, there is no way we could ever have evidence.

If PI being irrational is a bug, we have no way to know that. We just day "that's the way it is, and we don't know why" and move on.

It's fun to think about, but no, we're not in a simulation. And even if we were, there's no way you'll ever prove it.

Aside from the obvious differences, car and aircraft design pull in completely opposite directions regarding weight. For a car crash protection is a high priority - that adds weight. Not something you want in an aircraft. Ditto airbags with explosive charges. A way this has been skirted is to license the vehicle on the ground as a quadricyle which doesn't need to meet many (any?) of the safety requirements of a car. But frankly I wouldn't want to drive one.

I really don't see the point of these vehicles - they're going to be compromised both on the ground and in the air and if you're rich enough to buy one you can probably afford a rolls or bentley than you can park beside your Bell or Sikorsky at the airport.

And that's why grocery delivery companies have the lifespan of a mayfly. It's been tried many, many times - and only works in wealthy high-density city centers.

It's basically the same model as the bicycle courier. You can probably count on one hand the number of places where that exists in the US.

The key to making this work is dropping the cost a *lot* (like less than a tenth of current costs), and some consistently good customer service in picking the food to deliver.
