Humanity is on the cusp of practically limitless energy via nuclear fusion and basically nobody is talking about it, which is nuts.

I left working in fusion because I was skeptical of the field's ability to progress, but my mind has totally changed (1/n) Humans have built >100 tokamak fusion devices, which use magnets to confine and heat fusion fuel. We've hit a peak energy out/energy in (Q) of ~.67

Empirically, it turns out that Q scales *kind of* with the magnetic field cubed. 2x the magnetic field, 8x the efficiency. (2/n)

Going away for a long weekend with people makes you bond so much closer with them vs. something like hanging out from time to time/traditional friendmaking. Even if you sit around doing remote work or doing nothing most of the time. Seems like something people should do more of. Did this recently with a group of people and even though I spent maybe only a few hours with each person individually, walking in nature or just working at a table together, I feel WAY closer with them vs. if we had gotten dinner and had deep conversation 5 times over 6 months
