[MCU] What would have changed if Tony Stark had never escaped the cave and become Iron Man?

On mobile so I’ll just list some really instrumental shit Tony has been involved in

Maximoffs don’t seek revenge since Tony is already dead. Probably never volunteer for the program. 

Ultron and subsequently Vision are not created. 

No war machine. 

Peter Parker is never tracked down to join up and probably just remains a super lower level hero with no sweet suit. 

So off the bat you have several avengers and villains that just don’t exist. 

No whip lash and Killian probably still does extremis but who knows to what end.
