He was squarely wrong in that he made concrete predictions and these fell off dramatically.
He said in the early 90's that x86 would be dead in 5 years. If that's not a wrong prediction I don't know what is.
As for microkernels being superior to macrokernels, the trend has been to evolve into hybrid kernels (one of which Linux is now in practice). CISC vs RISC: same outcome. Hybrid approaches have come on top. Modern x86 processors are RISC inside, CISC outside and this produces concrete advantages by needing less memory bandwidth. Even if the instruction set was nominally RISC, we'd do more instruction pipelining producing a similar result. It's got to the point where the difference is nominal. We still call them x86 but they are fundamentally different processors. We still call them RISC and they do instruction compositing now.
He was WRONG with capitals, as usually "religious" and opinionated people are. There's rarely black and white in the real world. It's shades of grey.
Also, being off by a 400% in time scale, even if the outcome is similar as predicted, is being wrong no ifs or buts. Predictions like this mean total practical failure in any decision making.
