The error correction adds another factor of at least 100 or so in both qubits and gates needed (but possibly much bigger than 100, depending on qubit quality), see for example https://arxiv.org/abs/1312.2316. Other fields of application - factoring large integers, for example - takes many many more qubits to be interesting.
