I dunno. A lot of the investors were (are) on waverides from previous success. There are absolutely loan-backed ones, but as one startup investor said to me “I look for 200-300% return in 5 years to not call something a failure.” With expectations like that, you hold to record profits even if 2/3 the companies you invest in fail.
I agree, I love the idea of a brain chip, but not if someone can change licensing terms on something that’s INSTALLED in me.
