Mega task - as in have a hundred tabs open, a dozen Excel spreadsheets plus Outlook. Maybe there will be lots of cores since there is no more Moore's law, 32 core computing will be the new core i5 with 64 core computing being the new i7. Some software might run albeit slowly on older computers that only have 16 cores.
In this future the choice of 64 core computing is one of those things like car choice. Obviously we need cars electronically restricted to 155, we would not consider a car that only did 120 or so. There is a theoretical scenario where that vital power is needed but it is not a rational decision based on cost benefit analysis.
Therefore you can expect a change over time to where core total becomes marketing.
