A question of time
Some of the guys at work occasionally provide answers to .net magazine’s “big question” feature. When they told me about the latest question that landed in their inboxes, I felt I just had to stick my oar in and provide my answer.
I’m publishing my response here, so that if they decide not to publish it in the magazine or on the website (or if they edit it down), I’ve got a public record of my stance on this very important topic.
The question is:
If you could send a message back to younger designer or developer self, what would it say? What professional advice would you give a younger you?
This is my answer:
Rather than send a message back to my younger self, I would destroy the message-sending technology immediately. The potential for universe-ending paradoxes is too great.
I know that it would be tempting to give some sort of knowledge of the future to my younger self, but it would be the equivalent of attempting to kill Hitler—that never ends well.
Any knowledge I supplied to my past self would cause my past self to behave differently, thereby either:
- destroying the timeline that my present self inhabits (assuming a branching many-worlds multiverse) or
- altering my present self, possibly to the extent that the message-sending technology never gets invented. Instant paradox.
But to answer your question, if I could send a message back to a younger designer or developer self, the professional advice I would give would be:
When, at some point in the future, you come across the technology capable of sending a message like this back to your past self, destroy it immediately!
But I know that you will not heed this advice. If you did, you wouldn’t be reading this.
On the other hand, I have no memory of ever receiving this message, so perhaps you did the right thing after all.
