Fab numbers are astronomical. "TSMC recently announced plans for a $19.5B 3nm plant for 2022". How can the next computing paradigm even take off when all the oxygen is depleted in chasing "proven" technologies?

- 6pac3rings 6y agoSearch for Nikkei article on TSMC and growth plans. Look for "cage" and "bird" search terms at that source.
- the8472 6y agoWhat are the other options you would want to replace those proven technologies with? Sure, there are better semiconductor materials but they're expensive and already used where it makes economical sense. Nanotubes or graphene can't be handled at scale yet. Superconductors need huge contraptions for cooling. Using organic molecules is messy, see OLED. Optical parts might help, but that is difficult with silicon which brings us back to the other semiconductor options. Spintronics are already being put to use but those things have eye-watering prices. Look at intel, even incremental changes can go wrong and cost you competitiveness.
- ArtWomb 6y agoClassic innovator's dilemma. I personally am biased to silicon optics after seeing a few impressive demos. Albeit in laboratory conditions, under controlled settings ;) Rise of the learning machines https://www.nature.com/articles/s41566-020-00748-w https://www.nature.com/articles/s41566-020-00748-w
- jlokier 6y agoThat's not as much money as it sounds for the industry. Apple revenue is more than that each month. There's enough money around. So it seems unlikely that the cost of TSMC silicon fabs would be the obstacle to others developing alternative computing paradigms.
