Of course you can. In fact, the user included a not- particularly upgradable or reparable Intel Macbook in the comparison. Compile times and upgradeability/reparability are not mutually exclusive. It is not wrong to highlight the tradeoff. But people are allowed to decide "I want to give up reparability for nearly 5x faster compiles." Which is what the person got when comparing to the prior generation Macbook with the same compiler.
