Of course there are still limits, the article was talking about the 2003 limit of 64k lines which has now been increased to 1m.

You can’t exceed these limits without being heavily alerted/warned by the application too.

Every spreadsheet application and database has these sort of limits anyway, eg:

* Google Sheets limits total cells, although can only handle a tiny fraction of what excel can.

* Postgres limits columns to 1600 (much less than excel)

* Mongo limits document size
