Direct observation of any quantum system in a state of superposition destroys the superposition and it's going to collapse it to a random state.
So far we've managed to create an algorithm for prime factorization that works better on quantum than on classic because we've come up with some clever tricks to tell something about the solution of the algorithm without taking a direct measurement. But that's it. Decades later, we still have to come up with similarly clever algorithms for anything else. After all the clickbait about "quantum will destroy encryption", we just moved to elliptical curves and we're still safe because nobody has yet managed to pull out an algorithm to break them.
The fact that after so many years of investments there are just a couple of actual quantum algorithms that work, and work better than their classical counterparts, shows that we've hit a wall.
Plus, the higher the number of qubits, the higher the entropy of the system, the more you'll have to spend in error correction algorithms that at some point may just cancel out the actual gains of going quantum.
