You can pick funds that have little exposure to tech, which probably isn't what you're asking, but is a safer bet than being too much in tech:

  - S&P 500 Ex-Technology ETF (Ticker: SPXT)
  - S&P 500 Equal Weight ETF (Ticker: RSP)
  - Vanguard Value Index (Ticker: VTV)
  - Vanguard Total Stock Market ETF (Ticker: VTI)
  - Vanguard High Dividend Yield ETF (Ticker: VYM)
  - Schwab US Dividend Equity (Ticker: SCHD)
  - Invesco S&P SmallCap 600 Revenue ETF (Ticker: RWJ)

Target Date Retirement Funds are also a safe(ish) bet, as they are broadly diversified and continuously rebalanced toward retirement
