I don't know how others feel, but as an Intel investor, I prefer that Intel use the capital they have now (their fabs) to generate maximal profit, rather than speculate on whether alternative ISAs will take over as a result of not exclusively making x86 chips. Your strategy involves foregoing profit now, in order to hopefully make up for it later. I think you're missing the important point that Intel can take away market share from TSMC using this strategy, thus succeeding regardless of whether x86 or ARM wins in the end.
