It never ceases to amaze me how far we can still take a piece of technology that was invented in the 50s.
That's like developing punch cards to the point where the holes are microscopic and can also store terabytes of data. It's almost Steampunk-y.
- Solid state is kinda like a microscopic punch card.
  
  So are optical discs
  
  Much more so than solid state.
  
  More like microscopic fidget bubble poppers.
  When the computer wants a bit to be a 1, it pops it down. When it wants it to be a 0, it pops it up.
  If it were like a punch card, it couldn’t be rewritten as writing to it would permanently damage the disc. A CD-RW is basically a microscopic punch card though, because the laser actually burns away material to write the data to the CD.
  
  They work through electron tunneling through a semiconductor, so something does go through them like an old punch card reader
  
  Current ones also store multiple charge levels per cell, so they're no longer one bit each. They have multiple levels of "punch" for what used to just be one bit.
- That's how most technology is:
  combustion engines - early 1900s, earlier if you count steam engines
  missiles - 13th century China, gunpowder was much earlier
  wind energy - windmills appeared in the 9th century, potentially as early as the 4th
  Almost everything we have today is due to incremental improvements from something much older.
- Talking about steam, steam-powered things are 2 thousand years old at least and we still use the technology when we crack atoms to make energy.
  
  What the Romans had wasn't comparable with an industrial steam engine. The working principle of steam pushing against a cylinder was similar, but they lacked the tools and metallurgy to build a steam cauldron that could be pressurized, so their steam engine could only do parlor tricks like opening a temple door once, and not perform real continuous work.
- This isn't unique to computing.
  Just about all of the products and technology we see are the results of generations of innovations and improvements.
  Look at the automobile, for example. It's really shaped my view of the significance of new industries; we could be stuck with them for the rest of human history.
