Sweden's Air Force is designed to be dispersed throughout the country and take off on short strips of highway. A VTOL aircraft has allot of extra weight it must carry. A fighter designed to take off in a short distance isn't. Don't assume that technology will always work. Smart Bombs still hit civilians, they just hit less of them.
Computers go haywire.
Advanced technologies may be unable to withstand field conditions. Avoid using too powerful of technologies. Many cyberpunk writers believe that the era of cyberpunk has already begun. It has a limited lifetime. After a while, a new era will replace the times of cyberpunk.
