I think the question that's more important is how big of a target are you? If you/your company/your co-worker are all ultimately nobodies, then it probably doesn't matter.
If you have highly desirable state secrets or advanced tech, then from a technical perspective you're probably out of luck.
Your problem might not even be the connection, but the device connecting.
Chinese (PRC) people will almost all have WeChat on their phone. It's not hard to imagine keeping a list of all Chinese citizens in the US who come back to china, catch messages that say "I have to work for several hours" and launch a targeted attack with Pegasus like software.
A border agent could say "your data or else."
If you buy an iPhone in China, that data, like complete backups, is probably open to the Chinese government probably unencrypted. I am not sure what happens when a person who bought an iPhone outside of china and brings it to china, or who sets their locality to PRC.
A password vault could be compelled to be opened.
So to answer your question, first we have to understand what you have of value and what your threat model is.
From an ultra paranoid perspective, no physical device with privileges should enter China and even the employees personal devices shouldn't have anything company related like 2fac codes.
From a completely practical perspective, connecting to a vpn on a laptop while tethering through a "state approved" vpn is probably fine.
I think most valley companies would give completely new devices for e-mail and meetings and maybe local development, but completely restrict prod access, then destroy those devices when the employee comes back, but maybe I misremember.
IANAD, but IMHO you cannot just sequence the virus in asymptomatic people - you have to sequence a randomized, sizable % of the whole positive population, including mild or severe cases, and the dead too. Only then you'll be able to "paint a picture" of the different strains' effects on humans and slap some confidence data to each identified strain. Your idea definitely looks promising though.
As an example, just look at the Play Market (the Android marketplace for apps and games). There you can find dozens of nearly identical clones of the same game, uploaded by different authors.
-> How will Vibed avoid drowning in similar low-value ideas and ensure the best ones actually surface?
There are at least a couple points in your message that I wanna address.
> genuine insight is very rare and extremely hard to identify.
Insights capable of spawning billion-dollar companies are hard to come-by, indeed! But the smaller the scope of the idea - the bigger number of insights in existence that you can work on. When you can have a PMF on an idea with TAM of $100M in a matter of days, and you don't need VC money to make it happen, AND you can test it out with a rep of the target audience - isn't that something worth pursuing?
> How do you prevent Vibed from becoming a graveyard of half-baked ideas, I mean projects that are trivial, already solved, or fundamentally flawed?
I think people would genuinely not be incentivised to be posting projects for already solved problems, UNLESS the solutions are not exactly accessible to them, which in turn makes those project potentially a good idea still. We are just starting out so I'm not going to pretend I know rn how we would solve every problem we hit along the way (yet I hope we hit many and for a long time, haha), but one of the best ways for us to get the CONTENT we want - would be to work on getting the PEOPLE we need on the platform. We are also pretty well-versed with AI too, so we will be able to do a great moderation too (including a check for past projects that are similar -> thus to discourage repetition and plagiarism).
Hope that answers your question(s).
