Bitcoin the Record Breaker
Bitcoin rose above $50,000 for the first time on Tuesday as Wall Street pushed further into record territory on mounting confidence of Covid-19 recovery.
Bitcoin surged to $50,547.70 in midday European trading as an increasing number of corporate heavyweights back the world's most popular virtual currency.

Wall Street came back from a three-day holiday weekend eager to catch up with earlier rallies in Europe and Asia, and all three major indices opened in record territory on Tuesday.
"Sentiment remains supported by the bullish backdrop of positive Covid-19 vaccine rollouts and cases trends, along with highly accommodative fiscal and monetary policies, with expectations of the passage of President Joe Biden's proposed $1.9-trillion relief package remaining elevated," said analysts at Charles Schwab brokerage.
While Biden's spending package is widely expected to pass through the Democrat-controlled Congress, analysts have warned it might not be as big as the $1.9 trillion he proposed.
Meanwhile, with Britain and the United States leading the way in rolling out vaccines at the same time as they see a sharp slowdown in new cases and deaths, there are growing calls for governments to lift strict containment measures and get life back to a semblance of normal.
The United States on Sunday reported its lowest daily infection number since October, as Britain easily hit a key target for immunising its highest-risk people.
The European Union -- which is struggling with its vaccine programme -- has ramped up plans to deliver more jabs.

Anglo-Australian miner BHP jumped 2.3 percent to 2,279 pence on news of soaring profit and a bumper dividend increase by the group.
AI is the Neat Handwriting of the Illiterate
A model in the hands of someone who has read the filing and walked the plant is a clerk. The same model, speaking for someone who has done neither, is a disguise. On AI slop, phantom citations and factslop, why finish stopped being evidence of work, and the containment layer KXCO built so a machine cannot speak as the institution until a source is attached.
Worthship: Do Not Conform to the Age
Worthship is the older English word for worship, and it means to ascribe worth. Bishop Robert Barron preached Romans 12 on 30 August. This essay follows the text into the prison letters, and puts two questions to a graph: do the four readings of that Sunday agree, and was Paul free or in chains when he wrote about despair?
The Truth in All Its Ugliness Must Survive
A majority vote does not determine the truth. Consensus is a mood, gossip is a sport, and a model will write the pretty version for free. Why the ugly number has to survive, why a record beats a dashboard, and what KXCO was built to keep standing when the room changes its mind.
Don't Be the Best, Be the Only: Winning in an AI World
AI is repricing competence downward. What it cannot reproduce is a life. The case for remaining non-fungible, why friction still produces the best ideas, and what it means to build AI systems that keep the human intellect in them.
