every new AI application amounts to coming up with a smart sounding way to prey and profit from the most vulnerable and gullable
The app Text With Jesus uses artificial intelligence and chatbots to offer spiritual guidance to users who are looking to connect with a higher power: on.nbc10.com/7XM8xrf
People can text with Jesus on a controversial new app. How does it work?
Artificial intelligence app Text With Jesus lets users chat with biblical figures and it is raising debate over faith and technology.

Just learned a bunch about MCP servers and how to use them locally both for dev tasks and internal company functionality on today's devBetter.com coaching call. There's some cool stuff in the Docker MCP toolkit and it's pretty easy to spin up your own MCP server with the #dotnet new templates.

Warning: Copilot and AI look slick, but don’t trust everything they spit out. They’re Junior Programmers — smart, but lacking real-world experience and best practices. Someday that’ll change, but for now you still need your own brain and judgment.
