Do you think US national debt is actually going to impact our portfolios in a long-term?

I saw sth about the US debt climbing higher and higher pretty much every week. Normally I try to filter out these kinda news cycle, but with numbers getting this huge, it’s hard not to wonder what the long-term play is here, in 5 years, in 10 years? The classic advice is just "ignore the noise, DCA into index funds, and chill." Historically, the market has kept grinding upward regardless of what’s happening with US national spending. But it's still pretty worrying what's gonna happen in a long term to investments ,the US economy or even economy on the global scale.
