Amazed by how much electronics design still is done on paper because the software tools don't exist. The datasheets are incomplete & the PCB editors don't have something as simple as a ruler. Units are still in inches & you have to draw a lot of sketches to figure out where a pad should go or what a missing dimension is from the datasheet.  

It's an industry which was passed up by the software revolution of the last 25 years. The average game does billions more calculations than the average EDA program does.  It could experience a monumental change from just bringing the software up to where photoshop was 20 years ago.  There was a huge boom in EDA investments in 1997, but it was like the self driving car investments of 2015.  A lot of money went chasing it, but there were no results.
