Solar sails will make deep space exploration possible. They solve a core constraint (propellant) and we're developing them now.
"A solar sail is a spaceship that uses the sun for propulsion. It is propelled ahead by reflecting light."

The great filter is not a natural law it's just an open ended hypothesis based on conjecture. Also just because one person thinks it's a solar sail doesn't mean it is. There's s microbiologist who thinks the red rain in India was alien microbes, that doesn't mean it's true.

I didn’t read the article as someone who was asserting a definite on anything; more asserting that non-definites should be more openly discussed & investigated. For someone who doesn’t know anything about the field, it appeared a healthy, helpful viewpoint to me. Do you disagree?

"Where we have strong emotions, we're liable to fool ourselves" -Carl Sagan He can say whatever he wants but being told "there's not enough evidence to support that assertion" is not censorship. It could be a spaceship sure, but all the evidence points to it being a rock.
