You have to learn to work with a little motion blur and shoot at the appropriate moment. You also have to learn to refrain from using long lenses that you can't hand hold. It's like shootng underwater- it requires doing things slightly differently than you would under normal conditions, but that doesn't mean it's the equipment's fault if your pictures suck.
Pic may not be very good, but it illustrates the point that you can work in low light at slow apertures with slow shutter speeds. ISO 400, f/5.6, shutter speed 1.5s. Shot in a cave with the only light from people's headlamps. Camera braced against a rock for support. Focusing had to be done by scale because there was basically no seeing through the viewfinder. There is motion blur, but remarkably little for a people photo at 1.5s. It's a usable photo. I didn't tell them to hold still, I just waited for the right moment.
Shutter speeds of 1/15 and 1/30 are perfectly workable, and at f/1.4 and ISO 400 that's pretty damn low light. You just have to make two changes to your shooting stile. First, wait until your subject isn't moving. Second, stop moving when you press the shutter button rather than just swinging the camera around spraying exposures.
To answer OP's question, I consider f/2.8 to be fast in a zoom or a prime over 200mm. Otherwise, anything under f/2.8.
