In a recent Slashdot poll, users were asked which what breakthrough was the most likely from the following list:

Time Travel

Human-Level AI

Immortality

World Peace

Sharks with Lasers

Most people said that World Peace didn’t stand a chance prompting this comment:

It is deeply depressing that from amongst a list of alternatives whose achievements are up there in the realms of magic/fantasy, the one thing that humans are capable of right now is seen in the poll results as by far the least possible.

I thought this was thought provoking, but what what really caught my eye was the first response:

Sharks with Lasers are achievable right now.

Let us never forget that no matter what great advances are on the future horizon, we could put lasers on sharks today.
