While it looks like copying Apple, it doesn't necessarily mean this is a bad idea. Google did produce TPUs so this isn't theirs first rodeo. Also Apple is using ARM so whatever are their improvements, others can potentially match. Of course the execution matters, but if the current trend continues it may well be an existential threat to Android and by extension, Google.

Apple uses the ARM ISA but entirely custom cores, so this is like saying "AMD is using x86_64, so Intel can match them".

A year ago, the hypothetical would have been "Intel is using x86_64, so AMD can match them".

The G3 and G4 chips were much faster in their time than comparable Pentiums, as well.

The M1 chip is faster, currently, but it's not invincible.

Its not only about the speed but the power draw at those speeds.

G3 and G4 chips also had a fair lead there at the time. At the time iBooks were getting twice the battery life of most x86 competitors at least.

Also, presumably this whole process didn't start this month. Developing a chip takes time. This article makes it sound as though this is well on its way to production.
