Please note that they said the cost of the proteins below 100 a kilo.
Then remember that the protein is the cheap part. It is spinning it into a fiber that costs money.
They did NOT say they can produce a fiber at $100 a kilo.

I agree, but they did state "We are rapidly approaching the key cost threshold for exponential proliferation." To me, this means that this is simply a matter of time until they reach that goal of $100 per kilo. Spiber Inc. has a good track record of meeting their goals.

Granted, you are likely right about them speaking only about proteins and I don't know the cost of spinning the proteins into yarn, but the little that I can understand of the process, it does not seem very expensive. Correct me if I am wrong, but i believe it is simply dissolving the proteins in a solvent and forcing the solution through an aperture at a controlled rate, similar to the way rayon or acrylic is made. There is probably a little more to it, but I doubt it would be enough to drive up cost outside of the initial purchase of the equipment and solvent (which I believe is a fluorinated alcohol in Spiber's case).
Either way, my point was that two separate, rival companies have cited the $100 per kilo production cost, so i felt that was a significant difference from the $100,000 per kilo cited in the CC, even with the part about them likely having come down in cost since.

One thing different between Spiber and BT.... Spiber actually has a fiber. It may not be much and it may not be very good but they have one.
BT has produced nothing but hype and rumors.

Spiber, as of a February 2015 presentation to the ImPACT board in Japan, stated that they plan on providing fibers with the strength of up to 1.6 GPa and toughness of up to 354 MJ/m^3 at the time of commercialization. This is not as good as the strength properties of Dragon Silk, but is better than Monster Silk. I would consider that a pretty good fiber.

Bolt Threads claimed in 2014, back when they were Refactored Materials, that their first product would be pure spider silk. They have since changed this statement, but during that time, they were able to provide samples of their product to Steve Vassallo, general partner of Foundation Capital. Seeing these samples and reviewing Bolt Thread’s processes convinced him to lead the initial Series B financing of the company in 2015, generating $40 million. They were also able to partner up with Unifi (UFI), a textile manufacturer in North Carolina, to work their fibers into textiles. They have also stated recently that they are already producing fibers at commercial scale. I have been told by a thirs source that their process is actually more efficient than Spiber's as well. Based on all of this, I cannot believe that they do not have a fiber.
