ELI5 if spider silk is multitudes the strength of steel, why isn't spider silk farmed to any degree?

If it is so much stronger, why hasn't it been farmed in any significant way? Surely we can see the benefits of it over steel. It's bio renewable, non invasive and requires very little upkeep for the silk.

The tensile strength of spider silk is greater than that of steel, but there are other aspects of materials that matter too, such as rigidity, heat and cold resistance, resistance to abrasives and chemicals, etc.

Besides, do you want to run a farm with thousands of spiders? 🕷
