Well, never is a long time. I guess the more interesting question (to me) is whether engineering challenges will be easily overcome so as to make quantum computer components cheap and ubiquitous, or if there's some innate difficulty to their production that will make them uncommon for everyday personal use.

People struggled for 40 years to make a blue LED.

Even if quantum computers required near zero temperatures, superconductors and such stuff, there is no reason why you couldn't have all that in a no-serviceable-parts-inside box if the economic incentives were strong enough.

Well the question really is economic incentives. If it is too hard to do (say, doesn't scale) or can be simulated efficiently-ish on a classical computer -- no one will do it.

I love your optimism.
