Your friend is right and then wrong.
Yes, turbocharged engines usually have lower static compression ratio. For example my Subaru had 8.5:1. While NA engine is typically 11 to 13. But why ?
To compensate for higher air pressure from turbocharger. To make more force you need more pressure that comes from explosion. By forcing more air in, you can add more fuel and generate more pressure.
Turbocharged engines tuned for performance need better octane fuel, because you are trying to compress air that is already compressed, meaning that temperature raises more quickly.

Well at this point physical games might as well be just CD, with single text file containing key. As most of them need day one updates from internet anyway.
Difference here is that Game Pass ir a subscription service, while Steam (atleast looks like) regular store, where you outright buy and own* the game.
Because of this, on PC physical media games are dead. Don't know if digital stores on console offer to buy game and not pay any subscription.

Extra electric load will result in extra fuel consumption. Approach you are suggesting wouldn't recoup lost energy, as it actually would require to spend more energy.
The real wasted energy from cars is heat. Only 20-40% of burnt fuels energy is converted in motion, the rest is pure heat. That's why cars need radiators, to get rid of this heat.
If you want energy savings, look for a way to capture this heat and convert that to electricity or something.
Also braking is a huge waste of energy. As brakes work by converting kinetic energy, which was gained burning fuel, into yet again - heat. To accelerate again you have to burn more fuel.
That's why electric cars have regenerative breaking, where it's literally doing acceleration but backwards. Instead of spending electricity to make car go faster, you slow down car to generate electricity.
And why electric cars are more efficient, as they converter almost 100% of their "fuel" into motion. There's very little waste heat.

Reply to Eli5: how do circuit board works by ots125
You start by having a fiberglass and resin board, that has copper foil "glued" on it. Then you remove the unnecessary copper (etching it) and you are left with copper that you need. Copper forms "wires" called traces, that are used yo connect components. Then you solder components to ends of these traces.
