Some time ago, I gave a talk about boring technology at Booking, which means choosing the simplest, stable and maintainable solution you can get away with for solving a problem at a given scale.
Apparently Dan McKinley has similar views, which he explained in Choose Boring Technology. The writeup explains nicely what boring technology is, and why to prefer this.
Never forget your mission, which is business, not technology. The technology is a necessary tool, but likely not your friend.
