@tomhillenbrand I really hope that 2022 is not the year everybody on the world gets to experience crypto.

[Jan Portisch @JanPortisch]

@tomhillenbrand Even if #USDT is overcollateralized in liquid assets, they cannot just dump billions of dollars without dragging the price of the underlying instruments.
As the value of the collateral falls, we get an undercollateralized "stable" coin entering a death spiral.

#Transformer models do cool things in NLP, and they can also help reducing the search space in #ontology, #schema, and #knowledgegraph #matching. 👉"KERMIT 🐸 A Transformer-Based Approach for Knowledge Graph Matching" https://t.co/j0LtwuUZOh @svenhertling @JanPortisch @dwsunima
