That's tiny bit of an exaggeration, maaaybe. Maybe completely prophetic, though!

That said, Instagram was run by just a dozen people back then, while it had hundreds of millions of users, right? So it's not a new data point.

Storing, retrieving, indexing, managing 280 char blobs (with links, threads, embeds) is not exactly the most hardcore of a problem domains.

Microblogs are the typical tutorial topic, and twitter's only "innovation" was to increase the text limit.
