No, everyone is not using AI for everything

https://substackcdn.com/image/fetch/$s_!n_r-!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F957dc207-33f4-4e66-a821-66f340c9a623_1424x1404.png
About one third of the US population actively uses AI, one third occasionally uses it, and one third never uses it, contradicting the narrative that everyone is using AI for everything. People's concerns about AI, such as job replacement and privacy violation, and skepticism about its usefulness are driving this limited adoption, with many preferring to opt out or use AI in a more controlled manner.

Measles surge in Utah sparks fears US could undo decades of progress

The only scalable delete in Postgres is DROP TABLE

https://planetscale-images.imgix.net/assets/postgres-table-update-delete-C_kRTY7t.png?auto=compress%2Cformat
Deleting large amounts of data in Postgres can be inefficient due to write and replication overhead, but using DROP TABLE or TRUNCATE can scale much better. Structuring your schema with partitioning and avoiding large bulk DELETE operations can prevent bloat and improve database health.

Perlisisms

Programming principles emphasize modularity, simplicity, and adaptability, while also highlighting the importance of understanding the underlying mechanisms of computation. Effective programming requires a balance between creativity, discipline, and attention to detail, as well as a willingness to learn and adapt to new technologies and ideas.
