"Technology is constantly advancing", I know it well.

I wonder how much easier my work (demonstration) would have been if this antenna had been around 15 years ago.

I can still recall the desperate, physically demanding installation of antennas on the roof of a department store in the rain in order to secure a route for the radio waves.

I even studied to build my own antenna with the same level of performance as this one.

What? The Radio Law? Sorry, I am an engineer, so I am a layman in the legal side.

I wonder what all those hardships I (we) went through were all about -- it's a very empty feeling.

I mentioned before that if we wait 20 years, anyone can get a "supercomputer with the same performance as at present".

If so, I wonder if I (we) have been fighting for the sake of "technological issues that will be solved in 20 years.

At least,

-- Our painful and severe demonstrations were a necessary sacrifice to advance the technology over those 20 years.

If I didn't think so, I wouldn't be doing it.
