Gotta say, the old school debate on filesystems vs databases will never get old for me - I always end up with more questions than answers after reading stuff like this.
Everything's old school, everything's new.
It's important to remember that the cloud is also invented by the old school and understanding the oscillation between client/server architectures vs local, and it's implication on topics of data and files is interesting too.
More questions means more learning until I learned there's no one right or wrong, just what works best, where, when, for how long, and what the tradeoffs are.
Quick wins/decisions are often bandaids that pile up in an different way.
