I believe ARM will be the future, developers should not ignore it. Qualcomm has been doing the Snapdragon Elite processors in Windows laptops for a bit now, and they are quite snappy - there is definitely something there. LTT had mostly positive reactions to the Snapdragon laptops they tested, and Apple silicone Macs are just so insanely powerful.
I told my help desk manager at work that I would like to be the pilot user when we start getting Surface laptops with the Snapdragon Elite processors. My past 3 work-issued HP Elitebooks (860 G6/G8/G11) on Intel have all been so disappointing.
Rosetta 2 is supposed to be available for older games only but I’m not sure how they’re planning to enforce that. Maybe some kind of whitelist? Either way it was a travesty that Valve didn’t bother before. Running what is essentially a full web browser through Rosetta couldn’t ever work well because of all of the recompilation already happening there.
