Investing all my life savings in just one ETF

I like to keep it simple, I'm investing all the money I can get in VT ETF, the all world ETF.

The idea here is to diversify as much as possible, VT invest in 10,000 companies in 50 countries, I think it's enough diversification.

I like VOO and VTI but they focus in US, I know several companies are global companies, but the main focus is US.

I'm worried about a trade war affecting the US economy, that's why I picked VT.

Anyone uses a similar strategy? Investing in a single ETF?
