Uncle Bob really wrote "disks are being replaced by RAM" in 2018 and expected us to take him seriously. My guy, SSDs and HDDs aren't going anywhere—volatility is kind of a dealbreaker when you want your data to, you know, exist after a reboot. RAM is literally wiped clean the moment you lose power, which is why we still need persistent storage. But sure, let's architect our entire system around a hypothetical future where we all have infinite non-volatile RAM and electricity never goes out. Classic case of getting so lost in architectural philosophy that you forget how computers actually work.
