They say spider silk is way stronger than the same amount of steel while also being elastic. What keeps us from creating spider silk for buildings, rockets, airplanes and what not? Do we really need spiders for that?

It’s the square cube rule. Scale it to twice as wide it gets 4x stronger but 8x heavier.

When you scale it up we already have materials that are stronger and lighter than spider silk would be.
