Once we get tired of SaaS, the market will create standalone expensive software.

Even if I have to say that the subscription model is pretty good for B2B: fixed expense per month, someone to bother if things don't work, instead of spending my own employees time keeping infra up and debugging bugs.

I don't like SaaS for my personal use, I prefer to pay once, keep forever and fix on my own (for similar reasons to why I like cooking my own food instead of ordering take out all the time).
