I mean this seems like an easy answer to me no? People in the past wouldn’t suspect you’re from the future, they’d think you were posessed or something. People in the future would be much more likely to think of time travel, plus they’d have records of old accents and stuff.

The technology behind it isn’t new, but The Thought Emporium is a Youtuber who:

1: DIY-d a genetically modified virus to cure his own lactose intolerance (successfully)

2: Is currently working on a biological computer that runs on animal neurons.

3: Has livestreams where the viewers submit ideas (like making tomatoes spicy) and he designs DNA to accomplish it.

Also he helped shut down a scam health product that contained radioactive material which isn’t particularly futuristic (actually it reminds me of the “radiation is good for you” craze in the early 20th century) but I wanted to mention it anyways.
