Active Discrete - Diodes

I suppose the most common active discrete components that electronic engineers are familiar with should be the versatile diode:

For a simple two-terminal dual junction semiconductor device with non-linear electrical properties, it may come as a surprise that there are literally a bunch of variants exhibiting different characteristics and used in varied applications.

Considering the fact that the diode had existed since the cold war era as a vacuum tube entity, imagine the progress it has made to arrive at the forms that it is today:

What will the future hold for semiconductor electronics as wafer technology and manufacturing reaches its physical limits? Nobody knows. One thing is for sure——diodes are here to stay for quite a while. As they said, "You've come a long way, baby!"
