I mean no one has an M series MacBook for more than 3 years yet so there's a bit of an unknown here. However, the engineering on these things leans towards "a very long time". They run cooler and the same family of chips have powered iDevices, some of which have had 7-10 year lifespans already. Think about an iPad which get used daily, for example.
A MacBook Air doesn't even have a fan that could break. Seems likely to last a long time. The monitor hinge is probably the part most likely to fail here.
