This won't be much of a post. It's more a squirreling away of words for the future... but I want to put it here on the blog - in public - for the sole and egotistical purpose of being able to gloat at some future date.
I'm not usually one for making predictions, but in this case I will make an exception. And the prediction is as follows: by the end of the decade (2020), the scientific consensus will be that there is life on Mars.
I realize all current evidence in that regard is circumstantial, sketchy and inconclusive, but lately there is so much of it coming together that it is starting to look like there may be something to it.
So, should life indeed be discovered on Mars, I will now be able to claim to be a visionary.
And if Mars is found to be desolate and dead, I'll merely delete this post and claim your archived version is a forgery.
Either way, I win! :-)
