A lot of my ETFs are tech heavy, should I diversify ETFs in other industries as well?

I’m a 22 year old investor and I’ve had my Roth IRA since early 2021. After doing research, I decided I’m just going to buy and hold ETFs for a long time as my Roth IRA is intended to be one of my retirement accounts. I’ve learned a lot in the past year, and now realize a lot of my ETFs are practically identical: VTI, VOO, SPY, etc. I plan to possibly sell off some of the ETFs and focus on 1-2 ETFs per industry. Tech, energy, oil, etc. Is this a smart move? Obviously ETFs are diversified on their own already, but I feel like having multiple tech heavy ETFs isn’t the smartest move. Should I be looking for ETFs in other industries? If so any pointers on ETFs to research? Thanks!
