90% VOO + 10% SMH for longterm (20 years +)

Hey everyone, I was thinking about putting $800 into VOO and $200 into SMH every month. I'm treating VOO as my "safe bet" and SMH as a riskier play, but I'm pretty confident that semiconductors are the future (and the present lol). As a side note, I don't plan on touching this invested money for probably 20 to 30 years. I'm 25 right now and might think about touching it when I hit 50.

Also, I was thinking about investing in the NASA ETF in the future once things cool down. I got lucky and sold at a 20% profit today before tomorrow's IPO. NASA might shoot up tomorrow, but it doesn't really give me much confidence; I feel like it's a bit overhyped and overbought right now. When the dust settles, I was thinking about maybe doing a split of 90% VOO, 5% NASA, and 5% SMH. What do you guys think?
