(𝟭/𝟯) The Modern .NET Show with @mikekistler.bsky.social covered why MCP deliberately keeps humans in the loop.
When an LLM wants to use a tool, it asks YOUR application for permission. You approve or deny.
The LLM can't go rogue and rm -rf your system. Brilliant design decision.

I grew up using Windows. I started with 3.11, and've used most versions since. What Dave says here is constructive criticism, and I agree with his points.
I don't use Linux and MacOS because "Microsoft = evil", I use those because they don't get in my way.

I once asked, over on Mastodon, whether it was time to move off of LibSyn, and @james.crid.land mentioned that it wasn't something to be too worried about.
But with LibSyn closing their own podcast (The Feed) without much fanfare, it might be time to migrate The Modern .NET Show.

Do you know what I really dislike about SOME (heavy emphasis on the SOME part) of the tech community?
"I learned the hardest, so you have to too."
