Computers
If you had a computer from 20 or 30 years ago, you probably already know just how much they’ve progressed. The very first computer took up the space of an entire room and was weak as all heck by today’s standards. However, they did some pretty amazing things with the first machine, such as perform basic math. Solitaire had yet to be made for the computer.
What’s even more astounding is that the processing power of computers used to send humans to the moon are several times less powerful than that in our smartphones. Yet, the only thing we can do on our phones and laptops is look at memes and leave hateful messages in the YouTube comments.
