Although the answer is literally yes, it is meaningfully no. I have a keyboard that uses plate mounted Cherry MX reds, not lubed, pre re-tool (so the stems are a smidgen wobbly), and otherwise unremarkable. It is now 10 years old. None of the switches have failed, and the most I had to do was replace the stock PBT keycaps with new ones because I had worn them down until they were smooth (very undesirable to type on). These keycaps seem to be better than the stock ones (a really cheap set of doubleshot-thick but dye sub colored I got for $30-some), and probably is at least another decade before I have to do it again. I am probably past the million mark on important keys like WASD or space.
