Agile, Patterns, Object-Oriented Design: who cares?

Was Agile just a fad? Does anybody still care about patterns anymore? Does object-oriented design still matter?

I was watching a video about city architecture and the famous architect Christopher Alexander, and it was interesting when they showed how he inspired software design patterns. Alexander continues to influence building design; does the "Gang of Four" also have the same impact? How about the Agile Manifesto? Did we go too far with OOD? Or... are these the foundations of software development?

Bonus question: What’s your experience with low-code/no-code platforms? Do they just offload software development to novices, or are they helpful to you?

Everyone and anyone are welcome to join as long as you are kind, supportive, and respectful of others. Zoom link will be posted at 12pm MDT.
