Didn't work here, just a bunch of colored squares on Safari, Chrome or Firefox. The latter actually managed to hang my machine. I could ssh to it but kill -9 wouldn't terminate Firefox.
Had to force reboot the machine, haven't done that in years.
How so? In my experience Apple products outlast their competitor by a long margin.
All my Macs have lasted about 6/7 years, meaning, being used everyday with latest software for paid work. Most still boot and work today, but are impractical.
Same with iPhones, usually stop using because lithium batteries have a 4/5 years life span.
Amazing and scary, this WebGL thing is.
