The problem with disabling the memory overcommit is that then the RAM is wasted. That can be worked around with setting up swap but then the disk space is wasted.
Every investment is somewhat of a ponzi scheme. With stocks or real estate you also rely on the fact that the economy will function in the future and future generations will buy them back from you.
> Powell cured the resulting inflation without causing a recession. He did that without adding anything to our national debt.
That doesn't actually seem like a huge achievement. Inflation is the rate of change so if you stop creating as much money out of thin air, then it's not really a surprise that prices don't increase as much.
Modern cars are horrible. I recently discovered that all new cars sold in the EU constantly beep at you for supposedly speeding, even though the system doesn’t work well, and it has to be turned off every time you start the car.
The reality is that expensive electricity in the EU is by design. The EU ETS imposes heavy taxes on fossil fuels (and they are set to increase even more), which in turn causes the price of electricity to rise. Fully renewable electricity generation is still a long way off, so this will continue for a long time. But it is entirely a self-imposed political problem and could easily be fixed by getting rid of the EU ETS or capping the price of emissions at a more reasonable level.
