If you could go back in time, what is the one thing you would change about computers or the internet?

In elaborate terms: you have the ability to change any one of the protocols, specifications, designs or standards of the above at their proposal stage or before their mass adoption. You may choose to modify or reject an existing one or create one by yourself.

Some users and I would have common ideas in mind, however I would love to see some esoteric ideas as well.
