"Fortunately, it seems the attack is pretty difficult to pull off"
To note, TechRadar is awful at explaining how the 99.9% of the world is unaffected. I'm nowhere near an expert in this area but....this is so far removed from normal life that you'd almost need to be a willing participant and have already given up control of your device. It's not like someone can just sit next to you and siphon it out like in the movies.

And, how exactly are they getting into your machine to run this 'remote software' in the first place, without you giving them access? If you are downloading crapware from shady sites and running them under an admin/root account, you have far greater issues than this vulnerability!
I have a M1 Mac Mini with 8GB RAM. I use it for surfing, occasionally editing RAW files from my DSLR in Affinity Photo and I have never found it sluggish. It definitely feels snappier than my Dell Precision Laptop with i7 Pro and 32 GB RAM from work. Now granted that my Dell Precision has anti virus and encryption enabled due to work.
Not that it was great to start with.
It's funny, people have Hollywood like impression of hackers. These attacks require multiple brute force tries (timing and side channel attacks) to retrieve anything that can compromise the security (encryption, authentication, authorization or repudiation). Most common high level programs have number of retries built in before they will lock you out from performing sensitive operations.
M3 processor has a switch that you can enable to turn off prefetching and it helps with constant time processing for crypto operations (for example comparing two data buffer values or compute hash on certain size of data). Constant time operation thwarts the attack that has gathered some press. M1 and M2 don't have that switch and may have to rely on additional proofing to avoid side channel leakage.
To be honest 99% of folks would just be fine even with M1 and M2. The attacker needs multiple things go their way before they can do anything useful and probability of all of them going attackers way is near zero (if you understand how probabilities work).
There is a nice article : https://www.zetter-zeroday.com/apple-chips/ which is much more informative. It requires some computer architecture background for the reader.

It is a common convention used here when folks want to share their experience. It is stylistically used in place of: "Hi, in my experience after n-years of dealing with Xā¦ "
This is the internet, you are encouraged to fact check and look at everything with skepticism! But don't hate on the comment because you are not used to the "style of the post."

I have a MBA 13" M2 and it's great with 8gb RAM.. but 512GB is def minimum for my use case, wish they brought back the wedge shape.
