@ Lex Fridman
Direct democracy, where people vote directly on laws, would be a better system for a civilization on Mars than representative democracy.
EM
Elon Musk
12/29/21
@ Lex Fridman
We need transparency in governance, ensuring that laws are understandable and that the populace is well-informed.

@ Lex Fridman
The danger of radiation is often overstated; for instance, during the Fukushima incident, concerns about radiation in California were unfounded.
EM
Elon Musk
12/29/21
@ Lex Fridman
I visited Fukushima after the disaster, donated a solar power system for a water treatment plant, and ate locally grown vegetables to demonstrate that the risk from radiation is exaggerated.
EM
Elon Musk
12/29/21
@ Lex Fridman
The impact of nuclear accidents is often exaggerated compared to the actual risk, which is relatively low.
EM
Elon Musk
12/29/21
@ Lex Fridman
People often misunderstand radiation, confusing different types and sources, such as photons from cell phones, which are not as dangerous as they think.
EM

@ Lex Fridman
Radiation is often used as a tool for fear-mongering, and understanding it better can help combat that fear.
EM
Elon Musk
12/29/21
@ Lex Fridman
To combat fear of nuclear energy, it's important to understand the actual risks and compare them to other energy sources, like coal, which is far more dangerous.
EM
Elon Musk
12/29/21
