This is why I only trust old equipment but sadly in near future I'll won't be able to use them. I personally believe that when computers, mobiles and softwares were at an early stage of development, real aim and priority was to improve the technology and make things better but once there is a lit of potential to earn billions, then this takes over every positive thinking and real aim becomes to improve technology in order to gain more control and influence.
It is because of this that civil aviation systems, at airports and in radars, use technology that is more than 50 years old. Of course they are making some updates, but always based on the technology designed for over 50 years.
They thus manage to ensure greater security, as hackers have more difficulty in invading these systems, which are "outdated" compared to what is used today.
