The hope is these machines will reduce the number of steps to produce advanced chips (<3nm logic and DRAM), and hopefully the time and money cost of production will be lower compated to the current lithography techniques. A lot of people are still skeptical because of the cost of the machines, the potential low yield, high energy consumption etc.. So we need to see till fabs adopt this (if ever) and if it's the way to go.

If this turns out to be a dead end it'll be a big problem for ASML at the first instance. Also it's going to be good news for China since the technology gap will not be opening further.
