WBT achieved 1MB on lab equipment and the industry gave a collective yawn - as it knows it is filamentary and at best a candidate in the crowded embedded space. Resulted in WBT trying to desperately find a market/customer, sending out samples willy nilly to disinterested parties. Managed to find a few universities happy to continue research on AI - and resulted in them betting the company on doing extensive design work on spec for a Korean company for some auto sensors.

Once 4DS produces 1MB chips on 300mm wafers using same equipment as the industry heavyweights, the big memory users/makers (think Apple, Google, Facebook) will be banging the door down - as there is nothing else like what 4DS has for Storage Class Memory.

"Once 4DS cracks this", the Company will be snapped up. Not only will you be feeling more relaxed about your investment, you will be feeling much wealthier.
