My observations:
Existing companies do tend to (but not always) stick with their legacy stack. It makes sense, it’s the safe option.
Start ups OTOH, have the freedom to choose a new and innovative stack and often do. Sometimes it works, sometimes it doesn’t. The ones that survive and thrive will likely be dated in another decade and be seen as the old guard with legacy stacks.
It’s the circle of life.
Definitely not 6 foot. But yes I do exceed size 11… by quite a large margin 😅
