It is fair to acknowledge that with new levels of technology something that we valued gets lost. Consider writing, before writing became widespread, people's memories had to be much more elaborate (remembering who owed who for example), oral storytelling culture was stronger and perhaps people with the best memories and oratory skills were the most valued in society. With writing that got lost. There are countless examples big and small where new bit of tech completely demolished something that was genuinely deeply valued. But you know what, people move on and find other valuable things to do and value. The reason why the 25 Field Medalists who signed the letter could do their work at all is because writing and books existed, probably because computers freed up their brains, and civilisational wealth paid their salaries. If solving maths problems gets automated, we'll definitely lose something. It shouldn't be trivialised and it will hurt. But I don't want to live in the world where we choose to block off the future in the service of protecting the feelings of those who lose out. If Maths is actually important (absurt to think that it isn't), then automating it surely must lead to unimaginable technological developments. How can we compare this future with the current state of solving 1/7 millennium problems every 30 years (at best). It sucks, we should acknowledge that, and go full speed ahead.

Week 1 of the OpenAI sprint: recap. Day 1: WIN Speed boost from ~30 to ~50 TPS for Sol and Astra. Most people use these models, so this is a clear win. Day 2: REJECTED Auto-review, API tiers, meeting notes, Decisions API. Honestly, all pretty useless to me. I'm always on bypass permissions anyway. Decisions API should just be included in the subscription, classifiers are dirt cheap. Day 3: WIN GPT-6 finally shipped to ChatGPT. This was genuinely great. Faster responses and web search too. Easily one of the best days. Day 4: REJECTED Tailscale support was apparently already there, just announced as a new feature. Instant steering is decent, but Sol Ultrafast is for the Pro tier. Not enough. Day 5: REJECTED Composer Predictions and Dots updates, both Pro only. These don't meet the criteria of being relevant to most users. Most people aren't on Pro. We need these features on Plus and lower tiers. Day 6: RESET Reset delivered. Fair enough, exactly what was promised. Day 7: REJECTED Default context increased to 500K when 1M was already available manually. No extra long-context fees when subscriptions never had them anyway. Basically fake improvements. Week 1 stats: 2 wins 4 rejected days 1 reset day + 1 bonus reset (on day 3 for Codex reaching 30M active users) The speed boost and GPT-6 in ChatGPT were the clear highlights. Everything else was either too limited, already available, or not really an improvement. Let's see what Week 2 brings.

The Mile Long Moving Sidewalk of the 1893 Chicago World’s Fair In 1893, visitors arriving at the World’s Columbian Exposition by steamer stepped off onto a long pier stretching into Lake Michigan. Instead of walking the half-mile to the White City, they paid a nickel and boarded the Great Wharf Moving Sidewalk — the first public moving walkway ever built. Period engineering accounts said the platforms could seat about 4,300 people and, when riders also stood, carry roughly 6,000 at once. Hourly throughput estimates ranged from about 32,000 to 40,000 people. Guinness World Records lists it as both the first and the longest moving walkway of its era. How it worked It was not a conveyor belt in the modern airport sense. Architect Joseph Lyman Silsbee and engineer Max E. Schmidt built a continuous loop of overlapping wooden platforms, each about twelve feet long, riding on ordinary railway trucks and wheels. Passengers stepped from a stationary platform onto a slow-moving section (about 2–3 mph), then onto a faster inner section (about 4–6 mph) lined with benches. You could sit the whole way, stand, or walk against the motion. The loop ran out the pier and back under a long shed that kept riders out of rain and sun. The ride was popular because it was cheap, continuous, and gave a breeze off the lake. By the close of the Exposition it had carried nearly a million people. The sidewalk sat beside the Peristyle, Casino, and Music Hall — the gleaming classical colonnade that framed the Court of Honor. After the Exposition closed, fire in January 1894 destroyed the Peristyle and damaged part of the pier. The sidewalk itself was later dismantled. The one major exception still standing is the Palace of Fine Arts, rebuilt in limestone and now the Museum of Science and Industry. The sidewalk was real engineering, It was also a prototype that never realized to city streets, which is why it still feels like a glimpse of a future that did not arrive. A larger, elevated version appeared at the 1900 Paris Exposition (the trottoir roulant). Airport moving walkways arrived decades later. Urban planners kept drawing multi-speed sidewalks for New York and other cities well into the twentieth century. None of those city-scale systems were built. The 1893 machine remains the most ambitious public version ever operated in the United States. The sidewalk was not erased from history. It was dismantled after the fair, photographed while it ran, and then mostly forgotten.

The stack, in one pass. • EVM for builders • native on-chain CLOB for the book • batch auctions for fair prints • consensus prices for mark / funding / liq • agent registry + vaults for machine traders ETH has composability. SOL has speed. Hyperliquid has the book. SVP is built to hold the book #SVPChain# #PerpDEX# #ComingSoon#
