Could not be more true, and lot of advance in technology ( if not the majority of it ) came from war and conflicts.
For example, the three most significant technological achievement of 20th century by and large came from military applications.
1. Energy and power production capability of mankind has been uniquely revolutionized through nuclear technology.
( I mean, many people still does not fully recognize the the extent of what we achieve through the development of nuclear technology. We literally mastered the most Supreme source of ( material ) power and energy in the whole universe. )
2. Digital technology revolution through computers which launched the human civilization in to a completely new age.
"WHEN historians examine the origins of the electronic digital
computer, they usually give top billing to the pioneering efforts of
the American scientists J. Presper Eckert and John W. Mauchly,
who built their Electronic Numerical Integrator and Computer
(ENIAC) during World War II. Eckert and Mauchly are justly and
widely honored as the men whose efforts and risks led to the first
machines recognizable as modern computers. They also founded
the first private computer systems company. But historians now
also recognize a lesser known history of the computer, one whose
roots run deep into the most sensitive and secret corners of a
modern military establishment."
Here is very interesting read about it
3. Information technology revolution through internet, which brought unprecedented changes to every aspect of life.
And there are other domains of which development, military applications and demand played a significant role. ( if not THE main role )
Just for example, in aviation we all know about this man for his innovation in turbojet engine technology.

Air Commodore Sir Frank Whittle.
And we can go and on.
However, this topic is super controversial. That is why I avoided it in my first post.
Bro, I always appreciate your straight forward honesty and 'bold statements'.
If you didn't bring it up I probably wouldn't write this.
Wars and conflicts even set off the Industrial revolution.
As Europe colonised the world with military might and extracted resources this poured so much wealth into their own countries.
British colonisation of India even set off the industrial revolution because India was pretty rich which poured wealth into the British Empire.
British colonisation was mainly done with not just diplomatic and economic efforts but also military.
Even in Australia it got colonised mainly with military force.
