Example of how HFTs would "eat up" money, at least in the past: many instruments trade on multiple exchanges. So when a trader wants to execute what is conceptually a single large order, in practice this order may need to be split

That's similar to the "ex fossil fuel" indices I mentioned. It does not eliminate or lower the weighting of big emitters. For example, airline companies are built around the burning of kerosene, but they don't own fossil

For a Mobiüs strip, the bug would find the world had been mirrored along the width of the strip if it made a round trip and came back to the same point. Other bugs that stayed behind would claim that the traveller itself had become mirrored

Even without global warming from greenhouse effects, there are limits. Starting at current world energy use of about 5e20 joules/year, and a modest 2% yearly growth, it would take only about 500 years to get to the level of power that
