i forgot about pic related. it's about transistor tech. the second showed in her video of these three is apparently the best, but i made a better one. the third, shown in pic related is making possible to create more compelx technology, the problem is electricity transmission. it's not high enough in and with the current known and used materials for transistors. so we have to research on materials because of that too. we are in the year 2022. nearly Q2 2022.
