I dont know if any specific model will be the right answer, but Qualcomm has their Snapdragon event going on right now, and many of the advancements they are touting are specifically for local AI processing.
So, computing power will improve significantly over the next few years, with AI being the largest benefactor.
A bit of an anecdote, but i was a long-time user of Mint, which integrated with all my banks and credit cards, which was nice.
When I decided to selfhost, I was disappointed that bank syncing wasn’t a thing, or it had these roundabout ways of working, or they simply didn’t support the banks and credit cards i use.
So… I ended up wity Money Manager EX.
Once i did the initial importing of my records, everything since has been manually entered.
Now, this might seem tedious depending on how many transactions and accounts you manage, but it’s really not.
Depending on how often you update your records, you can do an easy export/import of your transactions from your bank (usually a csv export). Doing this once a month isn’t terrible.
I just manually enter all my transactions. Yes, more work, but also less frustration and it makes me feel more in touch with my spending.
Even not having to worry about the hassle of syncing not working, or having to fix things like that is a huge weight off my shoulders.
Anyway, just wanted to share my experience because bank syncing shouldn’t be a make-or-break thing.
