This HAS to be trolling. You cannot be this illogical. The M1 in my 2 year old Air still beats an i9 in a laptop. The Studio kicks tha ass of most Intel boxes for a similar cost. But you're conjuring some BS about intel suddenly being twice as fast? GTFOH with that. And unless you are booked solid for months ahead, doing the work 2x as quickly doesn't double your supposed client list.
EDIT: The PowerPC era is irrelevant. Most of that happened prior to Jobs, all of it happened before Apple started acquiring chip expertise and it was TWENTY YEARS AGO. Of course AS needs to be as good and usually better than Intel. But whining that they aren't updating every 12 months (yet) and that if they don't do so in the next 3 months, they're DOOOMED is laughably transparent.
Finally, I hate to break this to you, but high end video work is a tiny percentage of the market. The Air is the largest seller in the Mac line and if Apple does nothing but match high end Intel performance but also give us that on a performance/watt basis that blows away Intel, the Air will continue to sell incredibly well. Even the MBPs will benefit because they are inherently portable so perf/watt DOES matter there. Go look at MKBHD's MBP 16 review video where he shows editing an 8K RAW file and how well it performs. And can do that for hours on battery power. Heck, here:
