Completely tangential:

I tried VMWire fusion to run multiple browsers to get tickets for Glastonbury.

Are virtual machines ever not slow?

Running 9 virtual machines on an M1 mac, did not work...

I needed to be able to take over at any point, to enter the credit card details etc if successful, so puppeteer would not have been a good solution.

I think I need to rent multiple devices just for the day it seems. Chrome offers multiple profiles so I had 9 browsers, but you only get 60 refreshes per minute n an IP address. I would need to redirect some of the chrome instances, and have the screen real estate to handle it.
