A good time for TSMC is about to come as it is doing what Intel is doing. Next generation is using ARM Architecture in all the electronic devices and if this works fine it will be a major step in breaking the monopoly of Intel in the computing environment.
Intel is a very good marketing company. Sure, it has great engineering als. The strides in Intel do not have much to do with process but its capacity to entice and keep partners in its technology ecosystem. If you cannot match that, you have no chance. Not sure this changes it but we celebrate this effort at least.
