Very patient of you

Ah, but that’s by design: it also acts as a soothing white noise machine.

Then you might point out the exhaust and all it’s associated wastes, but that’s by design: it produces a heady and aromatic product for recreational huffing.

Then you might point out the vibrations, but that’s by design: the engine also provides invigorating massages to relax taut muscles.

Yeah, of course! Because we’re all using… 👀

If you cast it so that it’s point of origin is 150ft away from you, then it would expand both 93ft towards you and 93ft away from you. By expanding 93ft towards you, there’d still be a gap of 57ft between you and the edge of the fireball. The farthest point edge of the fireball would be 243ft away.

So Fireball makes a 20ft radius sphere. That’s a sphere with a volume of 33,510.322 ft^3 A sphere 100 times bigger would be 3,351,032.2 ft^3 Such a sphere would have a radius of 92.832ft The range of fireball is 150ft, so you could safely cast it’s 100x magnitude counterpart. Of course this is a very simplified idea of what 100x magnitude fireball could do. For instance, does it do 100x the fire damage? ~2,800? That’s over 50.9x more than lava (which is ~55). Does that mean it’s 50.9x hotter than lava? Making it 35,630-61,080 C, 6-11x hotter than the surface of the sun? These calculations are all fast and loose as actual explosion calculations are too complicated for my little brain.

This is actually a really interesting one! It questions your faith in humanity. All everyone has to do is not pull the lever. If the remaining population of humanity is on the 33rd switch, then just 33 randomly selected people all have to not choose to kill anyone. But can you trust such a huge decision to a stranger? Will the person further down the tract trust them or kill more people to safeguard humanity?

Personally, I think one life is worth sparing humanity this risk of annihilation. I could live in a world where my life might be randomly sacrificed to safeguard humanity if it only happens once.
