While a physical dictionary is helpful for shared knowledge, your personal mental dictionary is customized based on your individual experiences. What words are in my mental dictionary might overlap with the mental dictionary of someone else who also speaks the same language, but there will also be a lot of differences between the content of our dictionaries.

Okazało się, że LSD ma wpływ na szlaki metaboliczne, które mają związek z neuroplastycznością. Dotyczy to między innymi związku znanego jako kinaza mTOR (od mechanistic Target Of Rapamycin). Chodzi tu o kluczową proteinę, mającą znaczenie w procesach fizjologicznych, która jest swoistym centrum odpowiadającym za neuroplastyczność, pamięć i uczenie się.

The mission of techno-optimists appears to be to pick up where the European and American empires of the 19th century left off, using technological, political and economic power to bully, coerce and bludgeon other societies into acquiescence.

For Andreessen, all this is supported, like colonialism, by a kind of social Darwinism. He sees an evolutionary war in which “smart people and smart societies outperform less smart ones on virtually every metric we can measure”.

Andreessen writes “technology doesn’t care about your ethnicity, race, religion, national origin, gender, sexuality, political views, height, weight, hair or lack thereof”. However, his talk of “America and her allies” and “our civilisation” suggests Andreessen himself cares quite a bit about these things. The West should, he implies, embrace its rightful place as the world’s technological (and civilisational) leader.

At a basic level, the promise of our supply-and-demand #capitalism is that those who want a good or service are willing to pay more for it. But that’s illogical, because those who want or need goods the most may not be able to pay top dollar for them.

The result of this flawed logic has been that even the threat of disruptions to #grain supply have driven prices high and placed populations in countries across Africa, the Middle East and Asia at risk of #hunger.

The #financialization of everything, including basic needs, is just one mechanism of #neoliberal capitalism, and it reveals the dangers of turning basic needs into commodities.

Grain as a weapon: Russia-Ukraine war reveals how capitalism fuels global hunger

The Ukraine war’s impact on food insecurity is critical, but there is more to the picture. The main problem is that capitalism allows food and other basic needs to become precarious commodities.
