To be fair it’s always a crapshoot whether the person at Walmart or BestBuy or wherever really knows their stuff or just has a personal bias.

Sounds like you’re doing good by folks but for a lot of people you’re going to have an uphill credibility battle mostly because they don’t know you.

I’m a professional software engineer that has done all sorts of things involving computers over the years … I’ll always hear people out and some do have some genuinely great advice/say things I would’ve said if somebody asked me (and almost definitely aren’t getting paid what they’re worth by these places). Others are just kinda blowing smoke … and I fear for the customers that listen to them lol.
