"You will probably get a barrage of remarks calling Kim a liar and that $30k per kilo for protein is ridiculous and Bolt Threads can make it much cheaper."
correct..except you left out that kim is an idiot as well..
"But you will never get any evidence or sources to support these claims."
the guy just cited you a forbes article dated yesterday, where bt is quoted as saying their costs are around $100 per kilo and expect to get it down another 60 bucks!...lol
so what do you present as support for your claim that its $30k a kilo?...some publication from over 3 yrs ago...and you want people to look at that as the most recent info available??...that's your advice??
