Those charts illustrate that even in the worst bear markets in the last 100 years, there were still tradable rallies after the bottom was reached. The same can be said for the bear market in gold in the 1980's, Japan in the 1990's, etc. One thing is for sure: it will take a new generation of investors to take the Nasdaq back to 5,000 (15-20 years from now). The same can be said in all the great bear markets (1929 crash, the nifty fifty stocks, gold in 1980, Nikkei in 1990). Time heals all wounds in the markets.
