  • You’re right, but I think there are some other benefits to doing away with the chain. I have an E-mountain bike and between chain stretch, chain damage, and mud I go through 2 chains per season plus a couple trail-side repairs. Also, no chain means you can optimize pedal speed/torque for each individual rider, and keep it in the ideal range all the time regardless of bike speed. Essentially it offers a much wider power band than gears and a chain. You could also optimize crank length for clearance instead of torque. The front chainring is also a big point of contact on mountain bikes, removing that could improve clearance with the right design. I’d also be interested in the regenerative braking - if I go on an Enduro ride I’m cooking my brakes on much of the downhill, regen could save those and recharge the battery at the same time. Maybe regen could even lead to a smaller battery and save some weight.

    Sure there are disadvantages - weight, complexity, efficiency, probably others too. I think with time those will improve though and this just might be a viable setup for certain use cases.











  • For better or for worse he’s got a lot of friends within openai. Sounds like many of them have threatened to resign if he’s gone. If he goes and starts a competing company without the ethical guardrails, I think it’s likely a lot of folks will follow him. He also has very tight ties to the investing community so he would likely be able to raise funds quickly. I think there’s a solid chance he could make a credible competitor to openai within the next 5 years, especially if they lose talent/money over this.





  • I live in the middle of nowhere and drive race cars on the weekend, I think we agree on a lot of things. I love having plenty of space, not a fan of close neighbors, apartment living or any of that shit.

    I still want cheap trains and micromobility though. Every once in awhile I need to go into the city and taking my ebike in on the train is so much better than driving. Also even if you still drive like normal, it would go so much smoother if all the city folks stuck to the train and got off the roads.

    Not saying cars should be more expensive, and definitely not saying city living is the way, but having better options for city folks only helps the situation for the rest of us.
