And likewise, competitors to Apple's laptops and workstations are very much going to continue to be relevant, and to improve and compete. The M1 has shown that power, battery life, and minimal heat production are more possible than ever. That doesn't mean end users will all suddenly drop everything and stop buying products from the competition. They'll just raise their expectations for future revisions.
Apple has captured 66% [1] of the profit in the cell phone industry. Other than Samsung in the US and other manufacturers in Asia, Apple has made the other companies a lot less relevant. When the iPhone shipped in 2007, Windows Phone, Blackberry, Nokia, Palm, Motorola and others were the giants in the industry; I'd argue none of what's left of these companies is relevant today.
The same thing will happen with laptops; we already caught a glimpse of this in Japan, where Apple became the #1 selling desktop when the M1 Mac mini started shipping [2].
As the price/performance and performance/watt becomes more obvious, Apple will make inroads with new customers and markets.

The discussion above was specifically about how the advance in performance of the A7[0] in 2013 changed things. Honestly I don't know the numbers for market or profit share in 2013 to compare to now, but for consumers the decisions are not wildly different, except for someone specifically comparing phones on CPU performance alone, and ignoring the other differences. Of course, some will also be affected by Apple's marketing of "the fastest smartphones" and that helps with selling phones.
To apply this to laptops is, in my opinion, much trickier. Now I can't speak for all consumers considering purchasing a laptop, but as technical as I am, performance/watt is not my number one consideration. It kind of is, indirectly, an important one. I don't want a hot, loud laptop, and I want some battery life. But things like playing demanding games, or compiling code with as many cores as I can throw at it are more important to me. That and price, being able to upgrade RAM and SSDs when the need arises, etc.
So I have a $950 laptop with a dedicated GPU, 8 cores, 16GB RAM, 1TB NVME SSD, and I can add RAM and another NVME SSD when the need arises. Of course, I only get about 4 hours of battery life, and I'd love more, but it isn't going to change my life much either way (it's freezing outside, I am almost always within range of an outlet!), and I can't give up all the other things that this laptop has that an M1 Macbook lacks, even if the performance/watt is much better.
