Yes, avoid.

Laptops with soldered in SSDs should definitely monitor their usage and take care with this.

This project seems more of an experiment than something everyone should run, but pretty cool nonetheless

From what I understand, the warning is about swap-out during heavy memory use.

You don't need to be superstitious here: disk activity, including writes in particular, can be measured. E.g. `iostat` or `vmstat` on Linux.

It's a very conservative warning. The application does not perform writes, so the application doesn't actually wear your SSD at all. The rest is just application-independent general hygiene.

Probably yes, use an external drive for that sort of thing
