While there are still risks for the economy from real estate, I think China has shown the ability to manage them. For one, they were able to slow-walk the Evergrande collapse and move developments to state-owned companies. If it should become necessary again they will repeat the process.

China can produce 65nm chipmaking gear domestically which is like 20 years behind the West. Even if they develop at twice the speed, this means in 10 years they will be where the West is today.
The question is rather, can the West keep the rate of progress? ASML has already warned that lost business from sanctions will impact their ability to invest in R&D.
