One of the statements we get from this figure is “The Scope Triangle means choosing two fixed constraints and adjusting the third”. It sound wise, but does it really work?

“If one day, I launch my startup, I will use language X instead of the crappy stack I have in my current job”.

I have heard this one more than once. And today I would like to discuss some items that I think should be considered when answering this question (“what stack should I choose for this greenfield project ?”), instead of only focusing on one’s favorite language.
