That's the thing: good ideas seem unlikely, otherwise everyone would be doing them. IBM certainly didn't expect the DOS deal to be world-changing.
Someone should write a book, "100 Decisive Tech Battles: From Ancient Times to the Present," a tongue in cheek reference to https://www.amazon.com/100-Decisive-Battles-Ancient-Present/...
The book is excellent, and analyzes battles with a clinical detachment not really found in most history texts.
But each battle is decisive: it shaped the world. There are many skirmishes that would be interesting to analyze but out of scope for the book. That's what makes it a fascinating collection.
If we had to think of 100 technology "battles" that reshaped the world, I wonder what they would be? There is so much freedom in the criteria that it's hard to know where to constrain it: Electricity, plumbing, grocery stores, etc have all shaped the world. Many had a "decisive" effect in that it was technology vs technology, and one tech came out the winner.
I think computing alone could fill a book of 100 tech battles, and it would be interesting to try. Which stories were decisive? It would take months to decide, but it would be enjoyable work.
