How much quantum computing capability do you actually need before it becomes useful for real problems?

Quantum computers exist but can't solve anything practical yet. What's the threshold where quantum suddenly becomes useful? 100 qubits? 1000?

Threshold depends on problem. Some problems might be useful with 1000-10000 logical qubits. Others need millions. Not single number
